[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-5As shown, a pile foundation steel cage steel bar welding fixing device comprises a ring-shaped track machine 1, on which a plurality of sliders 3 are movably connected, and an inserting tube 2 for inserting the end face of the steel bar is fixedly connected on the upper surface of the slider 3, and a clamping block 6 for clamping on the track machine 1 is inserted on one side of the slider 3. As shown in the figure, the clamping block 6 and the slider 3 are respectively clamped on the two sides of the track machine 1, and the clamping block 6 is fixed on the slider 3 by bolts, so that the inserting tube 2 can be installed on the track machine 1, and vice versa, the clamping block 6 and then the slider 3 can be disassembled, so as to facilitate the adjustment of the number of the clamping blocks 6 of the track machine 1, and to facilitate the adjustment according to the number of steel bars. Two sprocket wheels 7 are rotatably connected to the clamping block 6, and a pointer 17 is fixedly connected to the end face center of one of the sprocket wheels 7 extending outward, and a dial 8 is rotatably connected to the clamping block 6, which is sleeved on the extension part of one of the sprocket wheels 7 and is used to cooperate with the pointer 17 to measure the moving path of the clamping block 6, and a dial 8 for measuring the moving path of the clamping block 6 is rotatably connected inside the clamping block 6. The roller 12 is connected to the side wall of the track machine 1 in a rolling manner, and the axle of the roller 12 passes through the block 6 and extends outward to be fixedly connected with one end of the other sprocket 7. When the block 6 is connected to the track machine 1, the surface of the internal roller 12 is close to the inner wall of the track machine 1. Therefore, when the block 6 slides along the surface of the track machine 1, the roller 12 is driven to rotate, and then the roller 12 is used to drive the sprocket 7 connected to it to rotate. The two sprockets 7 are driven by chains, so the two sprockets 7 can rotate at the same time. Therefore, the pointer 17 connected to the sprocket 7 rotates on the dial 8. The number of rotations of the pointer 17 can be obtained by using the reading on the dial 8, and then the number of rotations of the sprocket 7 and the roller 12 can be obtained. By multiplying the number of rotations by the circumference of the dial 8, the stroke of the roller 12 on the outer wall of the track machine 1 can be obtained, and then the distribution angle of the two adjacent blocks 6 can be known, which is convenient for quickly adjusting the distribution spacing of the blocks 6, and the insert 2 on the slider 3 is convenient for fixing the end face of the steel bar.

[0024] In order to fix the insert cylinder 2 on the track machine 1: the other end of the other sprocket 7 is fixedly connected to a brake disc 15, and a brake pad 14 for rubbing the brake disc 15 is inserted on the clamping block 6, and one side of the brake pad 14 is fixedly connected to a plurality of limit blocks 9 that penetrate the clamping block 6, one of which is set in an L shape and is used for personnel to pull the brake pad 14, and a spring rod 13 connected to the brake pad 14 is fixedly connected to the clamping block 6, and the spring rod 13 is set parallel to the other limit block 9. As shown in the figure, the elastic thrust of the spring rod 13 is used to make the brake pad 14 fit the surface of the brake disc 15, which can prevent the brake disc 15 from rotating, thereby preventing the sprocket 7 connected thereto from rotating and the roller 12 at the corresponding position from rotating, thereby fixing the clamping block 6 on the track machine 1, on the contrary, the personnel pulls the L-shaped limit block 9 to enable the brake pad 14 to overcome the elastic force of the spring rod 13 and move to disengage from the brake disc 15, thereby releasing the lock on the brake disc 15, thereby enabling the roller 12 to roll on the outer wall of the track machine 1 and adjusting the position of the clamping block 6.

[0025] In order to ensure the fixation of the steel bars inserted in the insert tube 2: a plurality of clamping blocks 4 are embedded and rotatably connected at the upper and lower positions of the inner wall of the insert tube 2. The clamping blocks 4 are elastically hinged with the inner wall of the insert tube 2 through a turbine spring, and the clamping blocks 4 are V-shaped. A screw 5 is fixedly connected to the outer wall of the insert tube 2 between the upper and lower adjacent clamping blocks 4. A nut 10 is threadedly connected to the screw 5. A swivel 11 is rotatably connected to the outer wall of the nut 10. A traction rope 16 that passes through the outer wall of the insert tube 2 is connected between the outer wall of the swivel 11 and the swinging edge of the adjacent clamping block 4. The swivel 11 is Due to the traction effect of the two traction ropes 16, when the nut 10 rotates, the swivel 11 will not rotate. Therefore, when the nut 10 is rotated, the nut 10 drives the swivel 11 to move along the surface of the screw 5. During the movement of the swivel 11, the traction rope 16 passes through the outer wall of the insert tube 2. Therefore, the traction rope 16 generates a pulling force on one side of the clamping block 4, so that the clamping block 4 overcomes the elastic force of the turbine spring and rotates and swings, and then the surface of the steel bars of different sizes are clamped by the part of the clamping block 4 located in the insert tube 2, thereby further fixing the steel bars of different sizes in the insert tube 2.

[0026] Working principle: According to the number of steel bars on the side of the steel cage, the corresponding number of inserts 2 are installed on the track machine 1 by plugging the block 6 and the slider 3, and then the curvature and arc length between two adjacent steel bars are calculated, and the L-shaped limit block 9 is pulled to make the brake pad 14 disengage from the brake disc 15, and the locked state of the roller 12 is released. Then the personnel pushes the slider 3 and the block 6 to move on the track machine 1, and the cooperation of the pointer 17 and the dial 8 facilitates the personnel to read the arc length passed by the block 6 on the arc sliding path. After reaching the predetermined position, the limit block 9 is released, and the brake pad 14 is re-frictionally contacted with the brake disc 15 under the elastic extension and reset action of the spring rod 13, thereby realizing that the roller 12 is locked on the track machine 1, and then the personnel inserts one end of the steel bar into the insert 2.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
