Description

Technical Field

[0001] The present application relates to the field of tunnel construction technology, and in particular to a locking foot anchor pipe positioning fixture. Background Art

[0002] During tunnel construction, a steel arch frame needs to be arranged to support the tunnel in order to improve the support strength and stability of the tunnel. The steel arch frame is composed of multiple I-beams. In order to control the settlement of the steel arch frame when supporting the tunnel, it is also necessary to set a locking foot anchor pipe at the foot of the I-beam of the steel arch frame to position the I-beam and improve the stability of the steel arch frame. The insertion length, angle and height of the locking foot anchor pipe have certain design requirements.

[0003] At present, the locking foot anchor pipe is usually driven in at an angle and height by welding the positioning steel bars. However, the position angle of the positioning steel bars is fixed after welding, which places high technical requirements on the welding construction personnel. If the welding position angle of the positioning steel bars deviates, the locking foot anchor pipe will deviate or tilt during the drilling process, which directly affects the subsequent driving angle and height of the locking foot anchor pipe. There is a problem that the driving process of the locking foot anchor pipe is difficult. Utility Model Content

[0004] In order to reduce the difficulty of construction workers in the construction process of driving the locking foot anchor pipe, the present application provides a locking foot anchor pipe positioning fixture.

[0005] The present application provides a locking foot anchor pipe positioning fixture that adopts the following technical solution:

[0006] A locking foot anchor pipe positioning fixture comprises a clamping plate, a bolt and a nut, wherein the clamping plate is respectively abutted against two flanges of an I-beam in the length direction of the locking foot anchor pipe, and the clamping plate is provided with a through hole for the locking foot anchor pipe to pass through; the bolt is arranged on the clamping plate, and the nut thread is arranged on the bolt and is used to be tightened to the I-beam.

[0007] By adopting the above technical scheme, the construction personnel adjust the position of the pallet abutting the I-beam, and then tighten the nut so that the nut is pressed against the I-beam, and the pallet can be positioned on the I-beam by squeezing. By positioning the two pallets at different heights, a height difference can be made in the perforations on the two pallets, and then the locking foot anchor pipe is passed through the perforations on the two pallets, and the insertion height and angle of the locking foot anchor pipe can be controlled, reducing the possibility of the locking foot anchor pipe running off track, skewing, etc., and the construction personnel can adaptively adjust the height of the pallet on the I-beam during the process of inserting the locking foot anchor pipe, and then adjust the insertion height and angle of the locking foot anchor pipe at any time, effectively reducing the difficulty of the construction personnel in the construction process of inserting the locking foot anchor pipe.

[0014] Optionally, the clamping assembly includes a screw and an abutment plate, the screw is threadedly provided with two screws on the clamping plate, the two screws are respectively located at the upper and lower sides of the through hole, and the abutment plate is provided on the screw.

[0015] By adopting the above technical solution, after the construction workers pass the locking foot anchor pipe through the through hole, they screw the two screws so that the two screws drive the two abutment plates to approach each other.

[0016] Optionally, the abutment plate is hingedly arranged on a screw rod, and a locking component for locking the abutment plate is arranged on the screw rod.

[0017] By adopting the above technical solution, by hingedly installing the abutment plate on the screw rod, the construction personnel adjust the abutment plate according to the inclination angle of the locking foot anchor pipe, and then lock the abutment plate on the screw rod through the locking assembly, so that the inclination angle of the abutment plate and the locking foot anchor pipe can be adapted, thereby increasing the contact area between the abutment plate and the locking foot anchor pipe, and thereby improving the stability of the abutment plate clamping the locking foot anchor pipe.

[0018] Optionally, the locking assembly includes a locking cylinder and a locking rod, the locking cylinder is rotatably and hingedly arranged on the screw rod, the locking rod is threadedly arranged on the inner wall of the locking cylinder, and the locking rod is rotatably and hingedly arranged on the abutment plate.

[0019] By adopting the above technical solution, the construction personnel rotate the locking rod to make the locking rod move away from or close to the locking cylinder, and the locking rod can pull the abutment plate to rotate, thereby conveniently and quickly adjusting the angle of the abutment plate and positioning the abutment plate at the current angle.

[0020] Optionally, a rubber pad is provided on the card plate, and the rubber pad abuts against the I-beam.

[0021] By adopting the above technical solution, the rubber pad enhances the friction between the clamping plate and the I-beam, thereby increasing the stability of the clamping plate on the I-beam.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By positioning the two pallets at different heights, the perforations on the two pallets can have a height difference. Then, the locking foot anchor pipe is passed through the perforations on the two pallets, so that the driving height and angle of the locking foot anchor pipe can be controlled, reducing the possibility of deviation and skewness of the locking foot anchor pipe. In addition, the construction personnel can adaptively adjust the height of the pallet on the I-beam during the driving of the locking foot anchor pipe, and then adjust the driving height and angle of the locking foot anchor pipe at any time, effectively reducing the difficulty of the construction personnel in the construction process of driving the locking foot anchor pipe;

[0024] 2. The spring can drive the bolt to drive the nut to keep tight against the I-beam, thereby improving the stability of the bracket on the I-beam;

[0025] 3. The diameter of the through hole is larger than the diameter of the locking foot anchor pipe, which makes it easier for construction workers to adjust the different heights of the two pallets. The locking foot anchor pipe can smoothly and obliquely pass through the through hole, and then the locking foot anchor pipe can be clamped by the clamping assembly to improve the stability of the locking foot anchor pipe.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a locking foot anchor pipe positioning fixture.

[0032] Reference Figure 1 , Figure 2 The locking foot anchor pipe positioning fixture includes a clamping plate 1, a bolt 2, a nut 3, a tightening component 4, a clamping component 6 and a locking component 7.

[0033] Reference Figure 1 , Figure 2 The clamping plate 1 is respectively abutted against the front and rear flanges of the I-beam in the length direction of the locking foot anchor pipe. The width of the clamping plate 1 is greater than the width of the I-beam. A through hole 11 is respectively opened on both sides of the width direction of the clamping plate 1. The diameter of the through hole 11 is greater than the diameter of the locking foot anchor pipe, so that the construction workers can smoothly pass the locking foot anchor pipes with different inclination angles through the through hole 11; the bolt 2 is installed on the clamping plate 1, and the nut 3 is threadedly installed on the bolt 2, and the nut 3 is tightly pressed against the inner side of the flange of the I-beam; the clamping assembly 6 is installed on the clamping plate 1, and the clamping assembly 6 is used to clamp the locking foot anchor pipe.

[0034] The construction personnel place the two clamping plates 1 against the front and rear flanges of the I-beam in the length direction of the locking foot anchor pipe, adjust the positions of the two clamping plates 1, and then tighten the nuts 3 so that the nuts 3 are pressed against the I-beam. At this time, the nuts 3 and the clamping plates 1 are respectively pressed against the two sides of the flanges of the I-beam, and then the clamping plates 1 are positioned on the I-beam. When the locking foot anchor pipe needs to be driven in at an angle, the construction personnel adjust the two clamping plates 1 to different heights, and the through holes 11 on the two clamping plates 1 can have a height difference. The locking foot anchor pipe is passed through the through holes 11 on the two clamping plates 1 in turn, and the locking foot anchor pipe is clamped. The holding component 6 clamps the locking foot anchor pipe to improve the stability of the locking foot anchor pipe. According to the height of the clamping plate 1 on the I-beam and the height difference between the two clamping plates 1, the height and inclination angle of the locking foot anchor pipe can be controlled, reducing the possibility of the locking foot anchor pipe running off track or tilting. In the process of driving the locking foot anchor pipe, the construction personnel loosen the nut 3 and adjust the height of the clamping plate 1 on the I-beam, so as to adaptively adjust the driving height and angle of the locking foot anchor pipe, effectively reducing the difficulty of the construction personnel in the construction process of driving the locking foot anchor pipe.

[0035] Reference Figure 1 , Figure 2 The side of the card plate 1 close to the I-beam is covered with a rubber pad, and the rubber pad is in close contact with the I-beam. The friction between the card plate 1 and the I-beam is increased by the high friction of the rubber pad, thereby enhancing the stability of the card plate 1 in close contact with the I-beam.

Two screw rods 61 are threadedly installed on both sides of the clamping plate 1, and each two screw rods 61 are respectively located on the upper and lower sides of the through hole 11; the abutment plate 62 is hingedly installed on the screw rod 61. In this embodiment, the side of the abutment plate 62 close to the adjacent abutment plate is an arc-shaped concave adapted to the locking foot anchor tube, so that the abutment plate 62 has a larger contact area with the locking foot anchor tube when clamping the locking foot anchor tube, thereby improving the stability of clamping and guiding the locking foot anchor tube; the locking assembly 7 is installed on the screw rod 61, and the locking assembly 7 is used to lock the angle of the abutment plate 62. The locking assembly 7 includes a locking cylinder 71 and a lock The fixed rod 72 and the locking cylinder 71 are rotatably and hingedly installed on the screw rod 61, and the inner wall of the locking cylinder 71 is threaded. In the present embodiment, a swivel is rotatably installed on the screw rod 61, and the locking cylinder 71 is hingedly installed on the swivel, thereby realizing the rotatable connection and hinge between the locking cylinder 71 and the screw rod 61; the locking rod 72 is threadedly installed on the inner wall of the locking cylinder 71, and the end of the locking rod 72 away from the locking cylinder 71 is rotatably and hingedly installed on the abutment plate 62. In the present embodiment, a hinge seat is hingedly installed on the abutment plate 62, and the locking rod 72 is rotatably installed on the hinge seat, thereby realizing the rotatable connection and hinge of the locking rod 72 on the abutment plate 62.

[0037] When the locking plate 72 is in the locked state, the locking plate 72 is locked and the locking plate 62 is locked.

[0038] Reference Figure 1 , Figure 2The clamping assembly 4 is installed on the bolt 2. The clamping assembly 4 is used to clamp to the inner side of the flange of the I-beam. The clamping assembly 4 includes a sleeve 41 and a spring 42. The sleeve 41 is threadedly sleeved on the bolt 2, and the spring 42 is installed on the end of the sleeve 41 away from the bolt 2; a protective tube 5 is also slidably sleeved on the sleeve 41, and the end of the spring 42 away from the bolt 2 is connected to the inner bottom wall of the protective tube 5.

[0039] After the construction personnel position the clamping plate 1 on the I-beam through the nut 3, they rotate the sleeve 41 to make the sleeve 41 away from the bolt 2. The sleeve 41 drives the protective tube 5 to abut against the inner side of the flange of the I-beam, and makes the spring 42 compressed. At this time, the spring 42 drives the protective tube 5 and the sleeve 41 away from each other, so that the protective tube 5 continues to press against the inner side of the flange of the I-beam, and the screw 61 drives the nut 3 to press against the I-beam continuously, thereby effectively enhancing the stability of the clamping plate 1 on the I-beam, and the action force of the spring 42 acts on the inner side of the flange of the I-beam through the protective tube 5, increasing the force area of ​​the spring 42 acting on the I-beam, improving the stability, and the protective tube 5 protects the spring 42 inside, improving the stability of the spring 42.

[0040] The implementation principle of a locking foot anchor pipe positioning fixture in an embodiment of the present application is as follows: the construction personnel, according to the height and inclination angle of the locking foot anchor pipe to be driven in, respectively abut the two clamping plates 1 on the two flanges of the I-beam in the length direction of the locking foot anchor pipe, and then tighten the nut 3 so that the nut 3 presses the inner side of the flange of the I-beam, and then tighten the sleeve 41 so that the protective tube 5 presses against the inner side of the flange of the I-beam, and position the clamping plate 1 on the I-beam, and then rotate the locking rod 72, adjust the angle of the abutment plate 62, and then pass the locking foot anchor pipe through the two through holes 11, and then screw the screw 61 so that the two abutment plates 62 clamp the locking foot anchor pipe, so that the driving height and angle of the locking foot anchor pipe can be controlled, reducing the possibility of the locking foot anchor pipe running off, skewing, etc., and can be adjusted at any time during the construction process, effectively reducing the difficulty of the construction personnel in the construction process of driving the locking foot anchor pipe.
