Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a pulley drive assembly for lifting equipment, which ensures that the transmission structure can be adjusted and used according to the use of the drive structure, so that the use of the pulley drive is extensive and improves To improve the working efficiency of the lifting equipment, in the process of using the gear to drive the sliding wheel, the two gears can be tightly fitted together to ensure the best transmission efficiency and avoid premature damage to the transmission teeth. In the transmission structure of the sliding wheel In case of an emergency during the process, the emergency braking process is carried out to ensure that the lifting equipment has a relatively safe lifting process during use, which can have a better protective effect on emergency braking, and can quickly remove the insurance to complete the emergency braking It solves the inconvenient adjustment of the currently used sliding wheel transmission structure, and the transmission efficiency cannot be adjusted according to the use of the transmission structure, which leads to limitations in the use of sliding wheel transmission and reduces the lifting equipment. Work efficiency, in the process of using the gear to drive the sliding wheel, the two gears cannot be tightly fitted together, which will cause damage to the transmission teeth of the sliding wheel during the transmission process, thus affecting the service life of the transmission teeth. An emergency may occur during the transmission structure, so it is necessary to perform emergency braking on the lifting equipment. It cannot guarantee that the lifting equipment will have a relatively safe lifting process during use. Before using the emergency braking, an insurance structure is required. Protect the emergency braking to avoid the braking phenomenon caused by the emergency braking without the action of the staff, and also ensure that the emergency braking operation can be performed quickly

Embodiment 1

[0027] see Figure 1-5 , a pulley drive assembly for lifting equipment, including a mounting frame 1, the middle part of the mounting frame 1 is fixedly connected with a first fixed shaft 2, and the side wall of the first fixed shaft 2 is rotatably connected with a first bevel gear 3, installed Both ends of the inner side of the frame 1 are fixedly connected with a mounting part 4, a sliding block 7 is slidably connected to the mounting part 4, a second fixed shaft 9 is fixedly connected between the two sliding blocks 7, and the side wall of the second fixed shaft 9 is rotatably connected. There is a winding wheel 10 and a second bevel gear 11, and the winding wheel 10 is fixedly connected to one end of the second bevel gear 11, the side wall of the mounting frame 1 is fixedly connected with a hydraulic cylinder 13, and the output end of the hydraulic cylinder 13 is fixedly connected with a U-shaped frame 16, and the U-shaped frame 16 slides through the inside of the installat...

Embodiment 2

[0030] see Figure 1-5 On the basis of Embodiment 1, a further improvement is made: a sliding groove 5 is provided in the middle of the mounting part 4, a guide column 6 is fixedly connected to the sliding groove 5, a sliding block 7 is slidably connected to the side wall of the guide column 6, and the guide column 6 A first spring 8 is fixedly installed on the side wall, and the first spring 8 is installed on the bottom end of the sliding block 7 .

[0031] In this embodiment, by installing the second fixed shaft 9 between the two sliding blocks 7, then the sliding block 7 slides in the sliding groove 5, and the sliding block 7 slides on the side wall of the guide column 6, and then utilizes the first spring 8 supports the sliding block 7, so as to stably drive the second fixed shaft 9 to move upward, thereby ensuring a better degree of meshing between the second bevel gear 11 and the first bevel gear 3.

Embodiment 3

[0033] see Figure 1-5 , made further improvement on the basis of Embodiment 1: the outer wall of the installation frame 1 is fixedly connected with a stable frame 12, and the hydraulic cylinder 13 is fixedly installed in the stable frame 12; one end of the first bevel gear 3 is fixedly connected with a fixed ring 14, One end of the fixed ring 14 is fixedly connected with a ball 15, and the other end of the mounting frame 1 is fixedly connected with a support ring 17, and the support ring 17 is supported on one end of the ball 15; the inner wall of the rotating ring 18 is fixedly connected with a bearing, and the bearing is fixedly connected with the first A side wall of the fixed shaft 2.

[0034] In this embodiment, the stability of the hydraulic cylinder 13 in use can be ensured by the stabilizer 12, which facilitates the operation of the hydraulic cylinder 13, and the first bevel gear 3 is easily supported on one end of the support ring 17 by the ball 15, ensuring To ensu...

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a pulley drive assembly for lifting equipment. Background technique [0002] The lifting equipment starts a vertical or vertical and horizontal working stroke after retrieving the material, unloads after reaching the destination, and then travels empty to the reclaiming location to complete a working cycle, and then carries out the second lifting or handling. Most of the lifting equipment starts to work vertically or vertically and horizontally after retrieving the material, unloads after arriving at the destination, and then travels to the reclaiming site in empty travel to complete a working cycle, and then performs the second lifting or handling. Generally speaking, when the lifting equipment is working, material retrieving, transportation and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent. Lifting equipment is ma...
