Description

Technical Field

[0001] The utility model relates to the field of pre-holes for cushion stones, in particular to a clamping device for pre-holes for cushion stones of bridge bearings. Background Art

[0002] According to the Technical Specifications for Highway Bridge and Culvert Construction and the requirements of the design drawings, the installation position requirements of the bridge bearings must be consistent with the design requirements to ensure that the bridge bearings are subjected to force. If the bridge bearings are not subjected to force or the force is uneven, the beam body will crack after casting, thereby causing damage to the beam body structure, seriously affecting the normal service life of the bridge, and also causing great safety hazards to the later operation of the bridge after it is opened to traffic. It is also quite troublesome and expensive to handle, so the installation of bridge bearings plays a very important role in our bridge operation safety and quality control.

[0003] The existing traditional process for reserved holes is to tie the embedded PVC pipe and the pad stone steel bar with lead wire. However, it is easy to be offset by the pressure measurement and vibration of concrete during construction, resulting in the position error of the reserved holes exceeding the standard. The existing pad stone support reserved hole fixture is not flexible enough to use. Not only can it not be adjusted according to the position of the reserved hole, but it also needs to fix each embedded pipe in turn, which greatly increases the workload of the operator and reduces work efficiency. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a bridge support pad stone reserved hole fixture, which aims to improve the problem that the existing reserved hole fixture is not flexible enough to use.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a bridge support cushion stone pre-hole clamp, comprising a clamp body, longitudinal slide rails are provided on the left and right sides of the clamp body, driving members are slidably connected to the upper and lower sides of the inner side walls of the longitudinal slide rails, the inner side wall of the left longitudinal slide rail is rotatably connected to the side threaded rod, the middle parts of the two driving members on the left are sleeved on the two sides of the side threaded rod, a transverse slide rail is fixedly connected between the two driving members, both sides of the transverse slide rails are slidably connected to moving members, the inner side wall of the upper transverse slide rail is rotatably connected to the upper threaded rod, the upper threaded rod passes through the outside of the transverse slide rail, the middle parts of the two moving members on the upper side are threadedly sleeved on the two sides of the upper threaded rod, the ends of the upper threaded rod and the side threaded rod are fixedly connected to rockers, and a positioning mechanism is provided on the moving member.

[0007] Preferably, the positioning mechanism comprises a fixing plate fixedly connected to the outer side wall of the moving part.

[0008] Preferably, a positioning hole is formed on the fixing plate, and push rods are rotatably connected to both sides of the positioning hole.

[0009] Preferably, the end of the push rod is fixedly connected with a clamping plate, and the clamping plate is arranged in the form of an arc-shaped plate.

[0010] Preferably, the transmission threads on both sides of the side threaded rod and the upper threaded rod have the same pitch and opposite thread directions.

[0011] Preferably, a connecting rod is slidably arranged between the upper and lower fixing plates.

[0012] The beneficial effects of the utility model are:

[0013] By setting up four fixing plates, it is possible to adjust the positions of the four fixing plates by rotating the side threaded rod and the upper threaded rod in sequence during use. When adjusted to a suitable position, the positioning holes on the fixing plates can fix the position of the embedded PVC pipes to avoid positional displacement. In addition, the adjustment of multiple fixing plates is synchronized in pairs without the need for individual adjustment. Four embedded PVC pipes can be fixed at one time, greatly improving the use efficiency of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example

[0022] Reference Figure 1-4 A bridge support pedestal stone pre-hole fixture, comprising a fixture body 1, longitudinal slide rails 2 are provided on both sides of the left and right sides of the fixture body 1, driving members 101 are slidably connected to the upper and lower sides of the inner wall of the longitudinal slide rail 2, the inner wall of the left longitudinal slide rail 2 is rotatably connected to the side threaded rod 201, the middle parts of the two left driving members 101 are sleeved on both sides of the side threaded rod 201, a transverse slide rail 102 is fixedly connected between the two driving members 101, both sides of the transverse slide rail 102 are slidably connected to moving members 105, the inner wall of the upper transverse slide rail 102 is rotatably connected to the upper threaded rod 103, and the upper threaded rod 103 passes through the outside of the transverse slide rail 102;

[0023] Furthermore, the middle parts of the two upper moving parts 105 are threadedly sleeved on both sides of the upper threaded rod 103, and the ends of the upper threaded rod 103 and the side threaded rod 201 are fixedly connected with the rocking wheel 104. The transmission threads on both sides of the side threaded rod 201 and the upper threaded rod 103 have the same pitch and opposite thread directions. A positioning mechanism is provided on the moving part 105, and the positioning mechanism includes a fixed plate 106 fixedly connected to the outer wall of the moving part 105, and a connecting rod 108 is slidably provided between the upper and lower fixed plates 106. A positioning hole 107 is opened on the fixed plate 106, and both sides of the positioning hole 107 are rotatably connected with a push rod 110, and the end of the push rod 110 is fixedly connected with a clamping plate 109, and the clamping plate 109 is set in an arc-shaped plate;

[0024] It should be noted that, through the arrangement of the four fixing plates 106, it is possible to adjust the positions of the four fixing plates 106 by successively rotating the side threaded rod 201 and the upper threaded rod 103 during use. When adjusted to a suitable position, the positioning holes 107 on the fixing plates 106 can fix the position of the embedded PVC pipe to prevent its position from shifting. In addition, the adjustment of the multiple fixing plates 106 is synchronized in pairs, without the need for individual adjustment. Four embedded PVC pipes can be fixed at one time, which greatly improves the use efficiency of the entire device.

[0025] The working principle of this bridge support pedestal stone reserved hole fixture:

[0026] During use, the operator can rotate the side threaded rod 201 by shaking the wheel 104 on the upper side of the clamp body 1. When the side threaded rod 201 rotates, the driving members 101 on the upper and lower sides will drive multiple fixed plates 106 to adjust the longitudinal positions on the transverse slide rail 102. When the longitudinal positions of the multiple fixed plates 106 are adjusted, the operator can rotate the upper threaded rod 103. When the upper threaded rod 103 rotates, the moving member 105 will drive the multiple fixed plates 106 to adjust the transverse positions. When the positions of the four fixed plates 106 are adjusted, the operator can insert the embedded PVC pipe into the positioning hole 107, and rotate the top rod 110 to make the clamp 109 clamp and fix the PVC pipe, so as to avoid the position displacement of the PVC pipe and ensure the position of the reserved hole is fixed.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
