In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "connection" and the like should be broadly understood, for example, "connection" can be fixed connection, can also be detachable connection, or integral connection; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] As shown in Figures 1-5 The present application provides a motor hoist installed in an elevator, which comprises a hoist body 1 and a sling 2 connected with the upper winding drum of the hoist body 1 at one end, and the bottom end of the sling 2 is connected with a hook. The hoist body 1 is installed on the top plate of the elevator frame 5, and a hole for vertical movement of the sling 2 is formed in the center of the top plate. The above is the existing structure of the motor hoist, which will not be described here.

[0030] In this embodiment, the motor hoist comprises an anti-sway mechanism 3 fixedly installed at the bottom end of the sling 2 near the hook, and an anti-sway pushing mechanism 4 for further supporting and stabilizing the sling 2 and transferring materials, which is specifically as follows:

[0031] The anti-swing mechanism 3 comprises a base disc 31, and the base disc 31 is provided with a central hole through which the sling 2 passes. In addition, the base disc 31 is provided with a slot 311, one end of the slot 311 is communicated with the central hole, and the other end penetrates the outer ring surface of the base disc 31 to allow the sling 2 to enter and exit the central hole. In addition, the slot 311 is slidably connected with a limiting clamping piece 312, and one end of the limiting clamping piece 312 facing the central hole is provided with a clamping tooth 3122 for increasing friction. The outer wall of the limiting clamping piece 312 is fixedly connected with a pair of positioning clamping blocks 3121, and the inner wall of the slot 311 is provided with a positioning clamping groove 3111 for sliding the positioning clamping blocks 3121, and one end of the positioning clamping groove 3111 penetrates the outer ring surface of the base disc 31. The base disc 31 is threadedly connected with a limiting shaft piece 313, the limiting shaft piece 313 comprises a threaded shaft portion 3131 threadedly connected with the inner wall of the base disc 31 and a stop ball 3132 fixed to the bottom end of the threaded shaft portion 3131 and pressing the positioning clamping blocks 3121. Since the stop ball 3132 has a spherical structure, the horizontal cross-sectional radius of the stop ball 3132 in the vertical direction is different, so that the limiting clamping piece 312 can be slowly pushed towards the central hole, and one end of the limiting clamping piece 312 provided with the clamping tooth 3122 is pressed against the sling 2, so that the base disc 31 is limitedly installed on the sling 2.

[0032] Further, the anti-swing mechanism 3 further comprises a support arm 32. The support arm 32 is symmetrically provided with two pairs, and the support arm 32 in the embodiment is a straight shaft that cannot be stretched, and in other embodiments, a telescopic rod structure with adjustable length can be replaced, so as to better adapt to the elevator frame 5.

[0033] The anti-swing mechanism 3 further comprises a sliding block 33 and a sliding rail 34. The sliding block 33 in the embodiment is fixed to the end of the support arm 32, and the fixing mode can adopt integral connection, bolt connection and the like. The sliding rail 34 is respectively fixed to the four vertical arms of the elevator frame 5 and vertically slides with the corresponding sliding block 33. When the material is lifted, the sliding block 33 vertically slides along the sliding rail 34, so that the anti-swing mechanism 3 always maintains a certain distance above the hook, and through the support of the four support arms 32 in four directions, the hook can be kept as much as possible in the center to avoid shaking when lifting.

[0034] The anti-swing pushing mechanism 4 comprises a fixed seat 41, a telescopic device 42 and a pushing block 43. The fixed seat 41 is an L-shaped structure, the vertical arm top end of which is fixedly connected with the lower surface of the base disc 31 and is fixed through a rib plate, the upper surface of the horizontal arm of which is fixedly installed with the telescopic device 42, and the telescopic device 42 can adopt a pneumatic cylinder, and when the pneumatic cylinder is adopted, the pushing block 43 is fixedly connected with the output shaft of the pneumatic cylinder.

[0035] The working principle of the embodiment is as follows: when the material required for installing the elevator on the steel structure is hoisted to the elevator frame 5 of the construction site (including hoisting from the lifting platform and directly hoisting from the ground), the anti-swing mechanism 3 is used to prevent the sling 2 from swinging and the anti-swing pushing mechanism 4 is used to push the sling 2 to the center of the hook. Figures 1-3With the lifting, the sliding block 33 slides along the sliding rail 34 vertically, so that the anti-swing mechanism 3 is always kept at a distance above the lifting hook, and through the support of the four support arms 32 in four directions, the lifting hook can be kept in the center as much as possible to avoid swinging during lifting.

[0036] When the material is lifted to the height of the floor platform 6, the piston rod of the telescopic device 42 is extended to cause the push block 43 to translate, and the push block 43 pushes the material to the direction of the floor platform 6 through the sleeving with the sling 2, so as to facilitate the workers on the floor platform 6 to receive the material.

[0037] In addition, the anti-swing mechanism 3 can be disassembled and replaced on the sling 2. Specifically, as shown in Figure 4 is taken as an example of installation, the sling 2 is slid into the center hole of the base disc 31 through the slot 311, then the limiting clamp 312 is horizontally slid into the slot 311, and the positioning block 3121 is ensured to slide into the positioning slot 3111. Then the limiting shaft 313 is rotated, the limiting shaft 313 is forced to move downward through the thread engagement between the threaded shaft part 3131 and the base disc 31, so that the blocking ball 3132 blocks the outside of the positioning block 3121 to limit the limiting clamp 312. Since the blocking ball 3132 is a spherical structure, the horizontal cross-sectional circle radius in the vertical direction is different, so the limiting clamp 312 can be slowly pushed to the center hole, so that one end of the limiting clamp 312 provided with the tooth 3122 is pressed against the sling 2, thereby limiting the installation of the base disc 31 on the sling 2. The support arm 32 and other structures are installed based on the base disc 31, so the entire anti-swing mechanism 3 is fixedly installed on the sling 2.

[0038] In summary, through the design of the anti-swing mechanism 3, the hanging sling 2 can be supported and stabilized, the swinging of the material during lifting is reduced, and through the sliding connection between the sliding block 33 and the sliding rail 34, the anti-swing mechanism 3 can move together with the sling 2, that is, move together with the lifting, and through the special structure design of the base disc 31, the anti-swing mechanism 3 can be disassembled and replaced on the sling 2; through the design of the anti-swing pushing mechanism 4, the material can be pushed to the floor platform through the extension of the telescopic device 42, so as to facilitate the workers on the platform to receive the material.

[0039] The above specific embodiments are only several optional embodiments of the present application, based on the technical solutions of the present application and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
