Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a small electric hoist, and more particularly to a small electric hoist installation structure. Background Technology

[0002] An electric hoist is a small, lightweight lifting device, typically installed on overhead cranes, gantry cranes, or I-beam rails, used for lifting heavy objects.

[0003] An existing electric hoist, such as the one disclosed in the Chinese Patent Database for preventing wire rope jamming (application number: 201410608232.5), includes an electric hoist housing and a protective plate that reduces the gap size to prevent the wire rope from getting stuck. A drum is installed inside the electric hoist housing. Sufficient gaps exist between the end faces of both sides of the drum and the inner end faces of both sides of the electric hoist housing to accommodate the wire rope. The front end of the protective plate is embedded in these gaps, and the left side of the protective plate is fixedly installed on the inner end face of the electric hoist housing. The distance from the right side of the protective plate to the end face of the drum is less than the diameter of the wire rope. The end of the protective plate extends outward through an opening in the electric hoist housing.

[0004] Currently, small electric hoists used in fixed positions are generally suspended from beams. During installation, a roughly U-shaped connecting sleeve is fitted onto the beam, with both ends of the sleeve fixed to the housing by screws. In actual use, if the screws loosen, the electric hoist will fall directly, posing a certain safety hazard. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highly safe installation structure for a small electric hoist.

[0006] The purpose of this utility model can be achieved through the following technical solution: a small electric hoist installation structure, the electric hoist including a cover set on the top, the installation structure including a frame, the frame including a horizontal beam set above the cover, a U-shaped connecting sleeve on the beam, and both ends of the connecting sleeve being fixed to the cover, characterized in that the beam is hollow, the top of the cover has a vertically set protruding column, the bottom of the beam is provided with a through hole for the upper end of the protruding column to extend into the inner cavity of the beam, the upper end sidewall of the protruding column is horizontally penetrated by a limiting groove along the length of the beam, the limiting groove including two groove sidewalls distributed vertically, a limiting rod is horizontally fixed inside the beam, the limiting rod passes through the limiting groove and is located between the two groove sidewalls.

[0007] The limiting rod, fixed inside the crossbeam, passes through the limiting groove and is positioned between the two side walls of the limiting groove. This ensures that even if the connecting sleeve and the cover are separated, the limiting rod will still abut against the upper side wall of the groove to support the cover upwards, thus effectively preventing the electric hoist from falling and ensuring high safety.

[0008] In the above-mentioned small electric hoist installation structure, the limiting groove is strip-shaped, and the length of the limiting groove extends vertically. The length of the limiting groove is greater than the outer diameter of the limiting rod. Under the premise of preventing the electric hoist from falling, the relative positional accuracy of the limiting rod and the protrusion can be reduced, thereby reducing the difficulty of processing and assembly.

[0009] In the above-mentioned installation structure of the small electric hoist, the protruding column and the cover are integrated into one piece, making the connection between the two more stable and reliable, thus reducing the chance of the hoist falling.

[0010] In the above-mentioned small electric hoist installation structure, the frame also includes a vertically arranged vertical beam, and both ends of the horizontal beam are open. The horizontal beam is fixed to one side of the vertical beam, and one end of the limiting rod is fixed to the vertical beam.

[0011] In the above-mentioned installation structure of the small electric hoist, one end of the limit rod is threadedly connected to the vertical beam to facilitate the assembly of the two.

[0012] In the above-mentioned small electric hoist installation structure, the vertical beam is hollow, and both ends of the vertical beam are also open, so as to reduce the weight and cost of the vertical beam at the same time.

[0013] In the above-mentioned small electric hoist installation structure, the cross-section of the vertical beam is square-ring. The vertical beam includes a beam side wall 1 and a beam side wall 2 distributed along the length of the horizontal beam, and the horizontal beam is fixed to the beam side wall 1. Both the beam side wall 1 and the beam side wall 2 are provided with clearance holes for one end of the limiting rod to pass through. Two nuts are screwed onto the limiting rod, and the two nuts are respectively pressed on both sides of the beam side wall 2.

[0014] Compared with existing technologies, the mounting structure of this small electric hoist has the following advantages:

[0015] 1. The limiting rod fixed in the crossbeam passes through the limiting groove and is located between the two side walls of the limiting groove. In this way, even if the connecting sleeve and the cover are separated, the limiting rod will still abut against the upper side wall of the groove to support the cover upward, thereby effectively preventing the electric hoist from falling and ensuring high safety.

[0016] 2. The length of the limiting groove is greater than the diameter of the limiting rod. While ensuring the electric hoist is protected from falling, it can also reduce the relative positional accuracy of the limiting rod and the protrusion, thereby reducing the difficulty of processing and assembly.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 As shown, in this small electric hoist installation structure, the electric hoist includes a cover 1 set on the top, and in the actual product, the main body of the electric hoist is supported by the cover 1.

[0023] This mounting structure includes a frame 2, which includes a horizontal beam 2a positioned above the housing 1. An inverted U-shaped connecting sleeve 5 is fitted onto the beam 2a, and both ends of the connecting sleeve 5 are fixedly connected to the housing 1. In the actual product, both ends of the connecting sleeve 5 are fixedly connected to the housing 1 by screws.

[0024] like Figures 1 to 3 As shown, the crossbeam 2a is hollow, and preferably, the vertical cross section of the crossbeam 2a is square-ringed. The top of the cover 1 has a vertically arranged protruding column 1a, and the bottom of the crossbeam 2a has a corresponding through hole for the upper end of the protruding column 1a to extend into the inner cavity of the crossbeam 2a. The upper side wall of the protruding column 1a is horizontally penetrated by a limiting groove 1b along the length of the crossbeam 2a. The limiting groove 1b includes two groove side walls 1b1 distributed vertically. A limiting rod 3 is horizontally fixed inside the crossbeam 2a. The limiting rod 3 passes through the limiting groove 1b and is located between the two groove side walls 1b1.

[0025] The limiting rod 3, which is fixed in the crossbeam 2a, passes through the limiting groove 1b and is located between the two side walls 1b1 of the limiting groove 1b. In this way, even if the connecting sleeve 5 and the cover 1 are separated, the limiting rod 3 will still abut against the upper side wall 1b1 to support the cover 1 upward, thereby effectively preventing the electric hoist from falling and ensuring high safety.

[0026] To further explain, the protruding post 1a and the cover 1 are an integral structure, making the connection between the two more stable and reliable, thus reducing the probability of the hoist falling. The limiting groove 1b is strip-shaped, and its length extends vertically. The length of the limiting groove 1b is greater than the outer diameter of the limiting rod 3. While achieving the premise of preventing the electric hoist from falling, it can also reduce the relative positional accuracy of the limiting rod 3 and the protruding post 1a, thereby reducing the difficulty of processing and assembly.

[0027] like Figure 1As shown, the frame 2 also includes a base 2b and a vertically arranged vertical beam 2c, with the lower end of the vertical beam 2c fixedly connected to the base 2b. Both ends of the crossbeam 2a are open, and the crossbeam 2a is fixed to one side of the vertical beam 2c, with one end of the limiting rod 3 fixedly connected to the vertical beam 2c.

[0028] In this embodiment,

[0029] The vertical beam 2c is hollow, and both ends of the vertical beam 2c are also open, in order to reduce the weight and cost of the vertical beam 2c. The horizontal beam 2a is welded to the vertical beam 2c.

[0030] like Figure 1 and Figure 3 As shown, one end of the limiting rod 3 is threadedly connected to the vertical beam 2c to facilitate assembly. Specifically, the cross-section of the vertical beam 2c is square-ring-shaped. The vertical beam 2c includes a beam sidewall 1 and a beam sidewall 2c1 distributed along the length of the horizontal beam 2a, and the horizontal beam 2a is fixedly connected to the beam sidewall 1. Both the beam sidewall 1 and the beam sidewall 2c1 are provided with clearance holes for one end of the limiting rod 3 to pass through. Two nuts 4 are screwed onto the limiting rod 3, and the two nuts 4 are respectively pressed against both sides of the beam sidewall 2c1.

[0031] In the actual product, the top wall of the cover 1 is attached to the bottom wall of the crossbeam 2a; there are two connecting sleeves 5, which are distributed along the length of the crossbeam 2a; there are two protruding columns 1a, which are also distributed along the length of the crossbeam 2a.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
