Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge deck crane installation technology, and in particular to an anchoring device for a bridge deck crane. Background Technology
[0002] The anchoring structure on a bridge crane is mainly used to fix all the crossbeams of the crane base to the bridge deck to ensure the stability and safety of the crane during operation. However, the existing anchoring equipment for bridge cranes has relatively poor adjustability during use, and therefore cannot adapt to the anchoring connection requirements of different crane crossbeams. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anchoring device for bridge deck cranes.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An anchoring device for a bridge deck crane includes a support base and a crane crossbeam. An adjustable double anchoring mechanism is provided between the support base and the crane crossbeam. The adjustable double anchoring mechanism includes a guide rail fixedly connected to the top outer wall of the support base, two sliding parts slidably connected to the guide rail, a bidirectional cylinder fixedly installed on the front outer wall of the support base, and two anchoring components sequentially disposed on the two sliding parts.
[0006] Both of the anchoring components include an anchoring seat fixedly connected to the top outer wall of the sliding member, a hollow anchoring rod fixedly embedded in the anchoring seat, a hydraulic rod fixedly installed on the bottom inner wall of the hollow anchoring rod, a threaded anchoring rod fixedly connected to the telescopic end of the hydraulic rod, and a reinforcing locking device located on the top of the anchoring seat.
[0007] Preferably, the two piston rods of the bidirectional cylinder are fixedly connected to the front outer walls of the two sliding parts, and the crane beam is provided with a connection port for the anchor rod.
[0008] Preferably, the outer walls of the two threaded anchor rods are slidably connected to the inner walls of the two hollow anchor rods, and both threaded anchor rods are fixedly connected to the crane beam by locking nuts.
[0009] Preferably, the reinforcing locking device includes a groove formed on the top of the anchor seat, a bidirectional screw rod rotatably installed in the groove, two centering rods symmetrically screwed to the two opposite threaded ends of the bidirectional screw rod, two arc-shaped locking parts symmetrically fixed to the outer wall of an adjacent side of the two centering rods, and a rotating cap fixedly connected to the outer wall of the front end of the bidirectional screw rod.
[0010] Preferably, the outer walls of both centering rods are slidably connected to the inner wall of the groove, and the two arc-shaped locking members are in contact with the upper surface of the hollow anchor rod.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. During the anchoring connection, the two piston rods of the two-way cylinder synchronously contract or extend to control the two sliding parts to move closer or further apart, thereby flexibly adjusting the anchoring position of the two anchoring components. Then, the two threaded anchor rods are controlled by two hydraulic rods to move up and down to flexibly adjust the anchoring height. This makes it easier to adapt to the anchoring connection requirements of different crane beams.
[0013] 2. This utility model is equipped with a reinforcing locking device, which uses the rotation of a bidirectional screw to cause two arc-shaped locking parts to center and lock the hollow anchor rod, thereby improving the firmness of the connection between the hollow anchor rod and the anchor seat and effectively preventing the anchor point from loosening.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1, referring to Figure 1-4 An anchoring device for a bridge deck crane includes a support base 1 and a crane crossbeam 2, with an adjustable double anchoring mechanism between the support base 1 and the crane crossbeam 2.
[0021] In this embodiment, the adjustable spacing double anchoring mechanism includes a guide rail 3 fixedly connected to the top outer wall of the support base 1, two sliding parts 4 slidably connected to the guide rail 3, a bidirectional cylinder 5 fixedly installed on the front outer wall of the support base 1, and two anchoring components sequentially disposed on the two sliding parts 4.
[0022] Furthermore, both anchoring components include an anchoring seat 6 fixedly connected to the top outer wall of the sliding member 4, a hollow anchoring rod 7 fixedly embedded in the anchoring seat 6, a hydraulic rod 8 fixedly installed on the bottom inner wall of the hollow anchoring rod 7, a threaded anchoring rod 9 fixedly connected to the telescopic end of the hydraulic rod 8, and a reinforcing locking device provided on the top of the anchoring seat 6.
[0023] Furthermore, the two piston rods of the bidirectional cylinder 5 are fixedly connected to the front outer walls of the two sliding parts 4 respectively. The crane beam 2 is provided with a connection port 16 for anchor rods. The outer walls of the two threaded anchor rods 9 are slidably connected to the inner walls of the two hollow anchor rods 7 respectively. Both threaded anchor rods 9 are fixedly connected to the crane beam 2 through locking nuts 10.
[0024] Furthermore, the reinforcing locking device includes a groove 11 opened on the top of the anchoring seat 6, a bidirectional screw 12 rotatably installed in the groove 11, two centering rods 13 symmetrically screwed to the two opposite threaded ends of the bidirectional screw 12, two arc-shaped locking parts 14 symmetrically fixed to the outer wall of the adjacent side of the two centering rods 13, and a rotating cap 15 fixedly connected to the outer wall of the front end of the bidirectional screw 12. The outer walls of the two centering rods 13 are slidably connected to the inner wall of the groove 11, and the two arc-shaped locking parts 14 are in contact with the upper surface of the hollow anchor rod 7.
[0025] The working principle of this embodiment is as follows: First, the two piston rods of the bidirectional cylinder 5 are synchronously contracted or extended to control the two sliding parts 4 to move closer or further apart, thereby enabling flexible adjustment of the anchoring position of the two anchoring components. Then, the two hydraulic rods 8 are used to control the two threaded anchor rods 9 to move up and down to flexibly adjust the anchoring height. This makes it easier to better adapt to the anchoring connection requirements of different crane beams 2.
[0026] Secondly, after adjustment, the two threaded anchor rods 9 are locked and fixed by the two locking nuts 10. Then, the bidirectional screw 12 is rotated by the rotating cap 15. Then, under the limit of the slide groove 11, the two centering rods 13 connected to the bidirectional screw 12 will drive the two arc-shaped locking parts 14 to center and lock the hollow anchor rod 7, thereby improving the firmness of the connection between the hollow anchor rod 7 and the anchor seat 6 and effectively preventing the anchor point from loosening.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
