Description

Technical Field

[0001] This utility model relates to the technical field of traction equipment for building steel bars, and in particular to a traction device for building steel bars. Background Technology

[0002] In the construction of building projects, steel bars are core load-bearing components, and the efficiency of their transportation and processing directly affects the overall construction progress. Among them, steel bar traction is a key process, which specifically refers to using specialized mechanical equipment to pull steel bars from the raw material storage area to the processing site or binding operation area. The application of this process not only significantly improves the automation and efficiency of steel bar transportation, but also effectively reduces material loss caused by collisions and bending during manual handling, and is widely used in modern building construction.

[0003] The existing rebar traction equipment consists of a rebar clamp, a traction frame, a support, and a drive device: one end of the rebar is fixedly installed on the traction frame by the rebar clamp, the traction frame is movably attached to the support through its bottom support, and the drive device provides power to drive the traction frame to move along the length of the support, thereby realizing continuous traction of the rebar.

[0004] However, the above structure has obvious defects in actual use: when the traction frame moves, its support part comes into direct contact with the surface of the bracket and generates continuous friction; after long-term operation, the contact area between the support part and the bracket is prone to deformation, cracks and other damage due to wear, affecting the stability and safety of the equipment operation; more importantly, since the support part of the bracket and the traction frame is designed to be in direct contact, when friction causes damage, the entire bracket needs to be replaced to restore the equipment function, which not only increases the complexity of maintenance operations and prolongs equipment downtime, but also significantly increases maintenance costs and is not conducive to the control of construction costs. Utility Model Content

[0005] The purpose of this invention is to provide a traction device for steel reinforcement in building construction, which eliminates the need to replace the entire support frame during maintenance, thereby facilitating maintenance and reducing maintenance costs.

[0006] The objective of this utility model is achieved through the following technical solution:

[0012] Furthermore, the traction frame has an internal accommodating chamber in which a driving component is installed; the traction frame has a first support portion and a second support portion on opposite sides; the first support portion is a sliding block with a flat and smooth bottom surface, and the sliding block overlaps on the overlapping surface of the pad; the second support portion includes a fixed shaft and a rolling element rotatably mounted on the fixed shaft; the rolling element can be fitted into a guide groove on the support rod; when the traction frame moves relative to the bracket, it drives the slider to slide on the overlapping surface of the pad and drives the rolling element to roll along the guide groove.

[0013] Furthermore, the driving component is a dual-head motor, which is fixedly installed in the accommodating chamber inside the traction frame.

Detailed Implementation

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] See Figures 1 to 8 This embodiment relates to a traction device for reinforcing steel bars in building construction, including a bracket and a traction frame 1 movably mounted on the bracket; the bracket has a support surface and a guide groove disposed on the support surface; the traction frame 1 has a first support part and a second support part, the first support part being movably supported on the support surface of the bracket, and the second support part being movably supported in the guide groove of the bracket; a transmission mechanism is provided between the traction frame 1 and the bracket, and a drive component with an output end connected to the transmission structure is provided on the traction frame 1.

[0031] When the drive unit is started, the traction frame 1 moves relative to the support through the transmission mechanism. Correspondingly, the first support part on the traction frame 1 moves on the support surface on the support, and the second support part on the traction frame 1 moves along the guide groove on the support. The traction frame 1 also has a connecting part 2, which is used to connect a steel bar clamp that can clamp steel bars and move with the traction frame 1.

[0032] The bracket is detachably provided with a pad 3 on the support surface, and the top of the pad 3 forms a flat and smooth overlapping surface; the first support part on the traction frame 1 is movably overlapped on the overlapping surface of the pad 3, and can move on the pad 3 when the traction frame 1 moves; the pad 3 can prevent the support surface on the bracket and the first support part of the traction frame 1 from directly contacting and causing friction damage. When the pad 3 is damaged, it can be disassembled and replaced separately without replacing the entire bracket, which is convenient for maintenance and reduces maintenance costs.

[0033] Specifically, the bracket includes two opposing support rods 8, a connecting beam 7 connecting one end of the two support rods 8, and a support leg 5 set at the bottom of the support rod 8; an opening is formed between the other ends of the two support rods 8; the top surface of the support rod 8 is a support surface; guide grooves are provided on opposite sides of the support surface of the two support rods 8, so that the cross-section of the support rod 8 forms an L shape; the pad 3 is fixed to the support surface of the support rod 8 by bolts 17, and a through hole 18 is provided on the support rod 8 for the bolt 17 to pass through; the bolt 17 passes through the through hole 18 from top to bottom through the support rod 8, and is locked at the bottom of the support rod 8 by a locking fastener.

[0034] The locking device includes a locking seat 13 and a locking nut 16. The locking seat 13 has an L-shaped cross-section. A through hole for the bolt is provided on the straight section of the locking seat 13. The vertical end of the locking seat 13 is formed by bending one side of the straight section. The straight section of the locking seat 13 is parallel to the bottom surface of the support rod 8, and the vertical end of the locking seat 13 is welded to the bottom surface of the support rod 8. After the bolt 17 passes through the bottom surface of the support rod 8, it passes through the through hole into the straight section of the locking seat 13 and is tightened by the locking nut 16. Because the traction device is exposed to the outdoor environment for a long time during daily use, the bolt 17 and the locking nut 16 are prone to rusting and cannot be separated during maintenance. A gap is formed between the straight section of the locking seat 13 and the bottom surface of the support rod 8, and an opening is provided on the vertical section of the locking seat 13 to connect the gap. The bolt 17 can be cut using the gap, so as to facilitate daily maintenance without replacing the entire support rod 8. At the same time, it avoids the locking nut 16 from contacting the bottom surface of the support rod 8 and causing friction damage.

[0035] It should be noted that the locking seat 13 with an L-shaped cross section is used in this embodiment. Depending on the actual situation, a locking seat 13 structure that can form a suitable gap for cutting the bolt can also be used instead, such as a locking seat 13 with a transverse U-shaped cross section.

[0036] The outrigger 5 is a vertically arranged elongated rod. The top of the outrigger 5 is fixedly connected to the support rod 8 via a connecting seat. The bottom of the outrigger 5 is provided with a leg plate 6. The leg plate 6 is a rectangular plate that can increase the contact area with the ground and improve the support stability. The connecting seat is a U-shaped seat with an open top, having two opposing side plates and a bottom plate connecting the bottom ends of the two side plates. A connecting cavity is formed inside the connecting seat. The support rod 8 fits into the connecting cavity inside the connecting seat through the top opening of the connecting seat and is tightened by horizontally locking bolts. When tightened, the bottom surface of the support rod 8 is in contact with the bottom wall of the connecting cavity, and the side surface of the support rod 8 is in contact with the side wall of the connecting cavity. The bottom surface of the bottom plate of the connecting seat is welded and fixed to the top of the outrigger 5.

[0037] The traction frame 1 has a box-like structure with an internal accommodating chamber where a drive component is installed. The traction frame 1 has a first support and a second support on opposite sides. Vertical plates 14 are located on opposite sides of the traction frame 1, and the second support is mounted on the vertical plates 14. The first support is a sliding block 9 protruding from the outer side of the traction frame 1, with a flat, smooth bottom surface. The sliding block 9 overlaps on the overlapping surface of the pad 3. The second support includes a fixed shaft and a rolling element rotatably mounted on the fixed shaft. The fixed shaft is fixedly connected to the vertical plate 14, allowing the rolling element at its end to engage with a guide groove on the support rod 8. When the traction frame 1 moves relative to the support, it drives the slider to slide on the overlapping surface of the pad 3, and drives the rolling element to roll along the guide groove. The first and second support components are used to support the traction frame 1... The two sides of the traction frame 1 form a supporting force, so that the traction frame 1 can be stably supported on the support and can move along the preset path on the support to complete the traction of the steel bars. The driving component is a double-headed motor 11, which is fixedly installed in the accommodating chamber inside the traction frame 1. The two output ends of the double-headed motor 11 extend laterally out of the traction frame 1. The transmission mechanism includes a drive gear 10 connected to the two output ends of the double-headed motor 11 and a rack 4 set in the guide groove on the two support rods 8. When the double-headed motor 11 starts, it forms a rotational motion, which is converted into linear motion through the meshing of the drive gear 10 and the rack 4 to drive the traction frame 1 to move relative to the support. Because a double-headed motor 11 is used, a driving force can be formed on the two sides of the traction frame 1 at the same time, so as to smoothly drive the traction frame 1 to move relative to the support.

[0038] In this embodiment, the rolling element is the driven gear 12, which meshes with the rack 4. When the traction frame 1 moves, the driven gear 12 can rotate accordingly following the movement of the traction frame 1.

[0039] A limit switch 15 is also provided on the traction frame 1. The limit switch 15 is used to control the working state of the drive component. When the traction frame 1 moves to the set position, the limit switch 15 is triggered to close, so that the drive component stops working, thereby realizing fixed-distance traction of the steel bar and avoiding excessive traction that could cause the steel bar to break or the equipment to be damaged.

[0040] The rebar clamp includes a receiving box 19, which forms a receiving chamber inside. A clamping component is installed in the receiving chamber. The receiving box 19 has a first clamping opening and a second clamping opening that connects to the receiving chamber. The rebar enters the receiving box 19 through the first clamping opening, passes through the clamping cavity formed inside the clamping component in the receiving chamber, and exits the receiving box 19 through the second clamping opening. A force-applying component is installed on the receiving box 19. The force-applying component is used to apply force to the clamping component from the outside of the receiving box 19 so that the clamping cavity formed inside the clamping component contracts to complete the clamping of the rebar.

[0041] The accommodating box 19 has a rectangular box structure. A first clamping opening is provided on the front side of the accommodating box 19, and the rear side of the accommodating box 1 is fixedly connected to the connecting part 2 of the traction frame 1. A second clamping opening is provided on the rear side of the accommodating box 19. The clamping components include a fixed plate 20 and a movable plate 21 arranged opposite each other. The fixed plate 20 is fixedly installed on the bottom wall of the accommodating chamber inside the accommodating box 19, and the movable plate 21 is movably arranged above the fixed plate 20. A clamping cavity is formed between the fixed plate 20 and the movable plate 21, and the first clamping opening and the second clamping opening communicate with the clamping cavity. Force is applied to the movable plate 21 by the force-applying component, and the movable plate 21 can move up and down in the accommodating chamber inside the accommodating box 19. The fixed plate 20 and the movable plate 21 are provided with arc-shaped grooves on their opposite surfaces. The arc-shaped grooves can cooperate with the reinforcing bars to increase the contact area with the outer circumference of the reinforcing bars, thereby improving the clamping force on the reinforcing bars.

[0042] The force-applying component includes a screw 22, with a rotating wheel 23 at the top end of the screw 22. The bottom end of the screw 22 is threadedly connected to the top of the housing 19 and extends into the housing chamber, rotatably connecting to the top surface of the movable plate 21. A stop nut 24 is threadedly connected to the screw 22. The top of the housing 19 is provided with a threaded through hole through which the screw 22 can pass and is threadedly engaged. The screw 22 forms a mating part 2201, and the top surface of the movable plate 21 is provided with a connecting cylinder 25 that can rotatably engage with the mating part 2201 on the screw 22. When the rotating wheel 23 is turned in the forward direction, it drives the screw 22 to rotate in the forward direction relative to the housing 19 and move vertically downward, driving the movable plate 21 to move closer to the fixed plate 20, the clamping cavity shrinks to clamp the steel bar, and the stop nut 24 is turned to lock the screw 22; after the steel bar traction is completed, the stop nut 24 is turned to unlock the screw 22, and the wheel is turned in the reverse direction, driving the screw 22 to rotate in the opposite direction relative to the housing 19 and move vertically upward, driving the movable plate 21 to move away from the fixed plate 20, the clamping cavity expands to release the steel bar.

[0043] In this embodiment, the fixed plate 20 and the movable plate 21 are provided with multiple arc-shaped grooves on their opposite surfaces. The arc-shaped grooves are arranged at equal intervals along the opposite surfaces to facilitate the traction of multiple steel bars and improve the traction efficiency.
