    • A pair of lock cylinders (60) for a backhoe slide frame (18) provide for a positive lock of the slide frame (18) in selected positions along rails (16A,16B). The rails (16A,16B) are generally horizontal and are vertically spaced. The lock cylinders (60) mount between the vertically spaced rails (16A,16B). The lock cylinders (60) each have a piston that acts to hold the slide frame (18) seated against the upper one of the rails (16A). The piston also provides a wedging action on at least one rail (16A) to hold the slide frame (18) from fore and aft movement relative to the rail (16A).
    • 用于反铲滑动框架(18)的一对锁芯(60)在滑轨(16A,16B)的选定位置提供滑动框架(18)的正锁定。 轨道(16A,16B)大致水平并且垂直间隔开。 锁芯(60)安装在垂直间隔开的导轨(16A,16B)之间。 锁缸(60)各自具有用于保持滑架(18)抵靠在上一个轨道(16A)上的活塞。 活塞还在至少一个轨道(16A)上提供楔入动作以将滑动框架(18)相对于轨道(16A)前后移动。

    • The invention provides that a vehicle (10) has connected to the front or the rear thereof a beam (16) which lies at right angles to the fore and aft direction of the vehicle (10). Mounted on the beam (16) is a cutting unit (24) for cutting a road surface (20), such cutting unit (24) being movable along the beam (16) so as to cut a transverse strip in the road surface (20) whilst it moves. The arrangement has jacking means whereby the beam (16) which has support legs (182, 184) can be jacked onto the ground so that the vehicle weight is taken by said legs (182, 184) to ensure stable cutting by the cutting unit (24). By sequentially raising and lowering the beam (16) and moving the cutter (24) along the beam (16), and by indexing the vehicle (10) forwardly or rearwardly, parallel strips can be cut in the road surface (20) in order to remove an area of the surfacing material for resurfacing or for gaining access to service pipes or the like. The cutter (24) is a drum which lies normally with its axis at right angles to the length direction of the beam (16), but it can be turned through 90° in a modified form of the invention, and the vehicle (10) can be moved forwardly or rearwardly with the cutter (24) in this position so as to cut a strip of road surfacing material in a direction of travel of the vehicle (10).
    • 本发明提供一种车辆(10),其前后连接有与车辆(10)的前后方向成直角的梁(16)。 安装在梁(16)上的是用于切割路面(20)的切割单元(24),该切割单元(24)可沿着梁(16)移动,从而切割路面(20)中的横向条 ),而它移动。 该布置具有顶起装置,由此具有支撑腿(182,184)的梁(16)可以被覆盖在地面上,使得车辆重量被所述腿部(182,184)所取,以确保切割单元的稳定切割( 24)。 通过顺序地升高和降低梁(16)并沿着梁(16)移动切割器(24),并且通过向前或向后分度车辆(10),可以依次在路面(20)上切割平行条 去除表面材料的区域,用于重铺或用于访问维修管道等。 刀具(24)是其轴线正交的方向与梁(16)的长度方向成直角的滚筒,但是可以以本发明的修改形式转动90度,并且车辆(10) 可以将刀具(24)向前或向后移动到该位置,以便在车辆(10)的行进方向上切割道路表面材料条。
