Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a loader traction mechanism for construction engineering. Background Art

[0002] Construction projects refer to housing construction and municipal infrastructure projects, their ancillary facilities, and the supporting lines, pipelines, and equipment installation projects. During the construction process of construction projects, loaders are needed. When a loader is fully loaded, it is inconvenient to move on a complex construction section relying solely on its own kinetic energy. Therefore, a traction mechanism is needed to tow the fully loaded loader.

[0003] The existing loader traction mechanism is to insert a plug with a gear hook into another plug with a gear groove. The gear hooks are engaged one by one into the gear grooves. At this time, the plug can be pulled to tow. During towing, multiple groups of gear hooks are engaged with the gear grooves, thereby ensuring that the two plugs are firmly installed and will not fall off during towing. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the gear meshing connection method will cause wear on the meshing part of the gear when the pulling force is large, thereby reducing the service life; while the hard pulling method does not save effort for the overall pulling, and the problem of insufficient traction power is prone to occur when pulling on some steep slopes.

[0005] The cam is fixedly provided with a first end in a forward direction and a second end in a reverse direction, and the cam is fixedly provided with a first end in a forward direction and a reverse direction, and the cam is fixedly provided with a first end in a reverse direction, and the reverse direction is reversed.

[0006] The engagement of the above parts can effectively achieve quick connection and quick release, and the two pulleys can effectively achieve labor-saving pulling and traction effect, thereby improving the convenience of traction and requiring less traction kinetic energy.

[0007] The utility model is further configured such that the connecting hook is designed in a "C" shape, the front end of the connecting hook is fixedly connected to the No. 2 pulley, the outside of the No. 2 pulley is slidably connected to the No. 2 steel cable, the No. 2 steel cable is fixedly connected to a pin near the left front end, and a tightening assembly is provided at the end of the No. 2 steel cable away from the pin, and the tightening assembly is used to tow the loader.

[0008] The present invention is further configured such that the limit assembly includes a No. 1 sliding groove, which is opened at the rear end of the clamping groove near the left side, and the No. 1 sliding groove is internally slidably connected to a limit block, and the left side of the limit block is rounded near the front end.

[0009] The utility model is further configured such that a No. 2 sliding groove is provided on the left side of the connecting block, the No. 2 sliding groove is connected to the No. 1 sliding groove, a pulling block is fixedly connected to the left side of the limit block, and the pulling block is slidably connected inside the No. 2 sliding groove.

[0010] The utility model is further configured such that the rear end of the limit block is fixedly connected to a damping rod, which is fixedly connected to the interior of the No. 1 sliding groove near the rear end, a No. 2 spring is sleeved on the outside of the damping rod, the front end of the No. 2 spring is fixedly connected to the rear end of the limit block, and the rear end of the No. 2 spring is fixedly connected to the interior of the No. 1 sliding groove near the rear end.

[0011] The above parts can be effectively engaged to avoid loose engagement and falling off, thereby improving the stability of the connection, ensuring that it will not fall off during traction, and reducing the power required for traction.

[0012] The utility model is further configured such that the top of the connection block is slidably connected to a limit pin near the clamping groove, and a positioning hole is provided on the top of the limit block near the front end.

[0013] The present invention is further configured such that a reel is provided at one end of the No. 2 steel cable away from the pin, the No. 2 steel cable is reeled outside the reel, and the bottom of the reel is rotatably connected to the top of the support plate.

[0014] The utility model is further configured such that a motor is fixedly connected to the top of the winding shaft, a support rod is fixedly connected to the top of the motor, the support rod is designed in an inverted "U" shape, and the bottom of the support rod is fixedly connected to the top of the support plate.

[0015] The loader that needs to be towed can be effectively moved through the winding method, and the winding pulling is combined with the pulling of the movable pulley to reduce the kinetic energy output, and the load-bearing weight is greater, and there are more usage scenarios.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The utility model allows the connecting rod to be embedded in the clamping groove, and the No. 1 spring can push the connecting block to reset, thus avoiding the danger of manual reset. After connection, the pin is embedded in the ground, and the winding assembly drives the No. 2 steel cable to shorten, thereby performing traction. The No. 2 pulley can share the gravity it bears, avoiding the problem of insufficient traction kinetic energy. This method of traction achieves the effect of winding traction, solves the problem of wear and tear that reduces the life of the traction mechanism due to gear meshing in the past, and increases the service life of the traction equipment.

[0018] 2. The utility model prevents the connecting rod from falling out of the clamping groove by pushing the limit block by the damping rod and the second spring. When the connecting rod needs to be disassembled, the pulling block can be moved to allow the limit block to retract into the first sliding groove. When the positioning hole reaches below the limit pin, the limit pin will slide into the positioning hole, thereby preventing the limit block from popping out, thereby removing the connecting rod from the clamping groove. This method of disassembly and installation achieves the effect of quick installation and disassembly, solves the problem of the previous single spring connection that the connecting rod is prone to falling out of the clamping groove when shaking, and improves the stability during towing;

[0019] 3. The utility model reels the No. 2 steel cable by rotating the reel driven by the motor, and the No. 2 steel cable can distribute the pulling force to the pin and the reel, thereby avoiding insufficient driving force of the motor. Traction in this way achieves the effect of labor-saving reeling and traction, solves the problem of insufficient traction force when traction on steep slopes through rigid reeling and traction in the past, and reduces the kinetic energy required for traction.
