Description

Technical Field

[0001] This utility model relates to the field of electric hoists, and in particular to a reinforced sprocket box. Background Technology

[0002] An electric hoist is a device used for lifting and moving heavy objects. It can be installed on various lifting devices such as monorail, double-rail, or cantilever cranes, and uses an electric motor drive system to achieve vertical lifting and horizontal movement of heavy objects within a certain range. For example, in a factory workshop, it can lift heavy machine parts from one work area to another, or move raw materials from a warehouse to the production line, greatly improving the efficiency of material handling.

[0003] Electric hoists typically include a motor, sprocket box, and gearbox. A lifting section is located on top of the sprocket box, used for installation, hoisting, and transport. This lifting section is usually integrally formed with the sprocket box, and its structural strength directly affects safety. Currently, some sprocket boxes on the market use cast steel to ensure strength, but cast steel is relatively heavy, resulting in a large overall weight for the electric hoist. Others use aluminum for the sprocket box, but this can lead to insufficient structural strength in the lifting section, making it prone to breakage and posing a safety hazard; this design needs further improvement. Utility Model Content

[0004] To further balance weight and structural strength and improve safety in use, this application provides a reinforced sprocket box.

[0005] This application provides a reinforced sprocket box, which adopts the following technical solution:

[0006] A reinforced sprocket box includes an aluminum sprocket box body, the top of which has a lifting part integrally formed therewith, and a reinforcing plate is embedded in the sprocket box body at the location corresponding to the lifting part, the reinforcing plate being a steel plate or an iron plate.

[0007] Optionally, both sides of the sprocket box body have mounting cavities, and a reinforcing plate is embedded at the bottom of the sprocket box body corresponding to the mounting cavity, and the reinforcing plate is fixed to the reinforcing plate.

[0008] Optionally, the reinforcing plate and the strengthening plate are integrally formed, and the reinforcing plate is a steel plate or an iron plate.

[0009] Optionally, the reinforcing plate has multiple through slots and notches.

[0010] Optionally, the end of the reinforcing plate has a protruding insert, and the reinforcing plate has a slot adapted to the insert.

[0011] Optionally, the top of the sprocket box body has a groove, the lifting part is set in the groove, two lifting parts are arranged in parallel, the lifting parts and the reinforcing plate are provided with through lifting holes, the lifting holes are symmetrically arranged on the lifting parts, and the two ends of the lifting parts are respectively fixed to the opposite side walls of the groove.

[0012] Optionally, the sidewall of the hoisting part has a recessed groove, and a reinforcing ridge is formed between adjacent grooves.

[0013] Optionally, the reinforcing ribs are distributed in multiple circumferentially spaced around the lifting holes.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. The aluminum sprocket box body is relatively lightweight. Combined with the embedded reinforcing plates and reinforcement plates, it effectively improves the overall structural strength of the sprocket box and the lifting part, effectively preventing the safety hazard of breakage due to insufficient structural strength at the lifting part. It well balances the weight and structural strength of the sprocket box and is suitable for large-tonnage electric hoists.

[0016] 2. The interlocking design of the reinforcing plate and the strengthening plate allows them to be manufactured separately, effectively reducing production difficulty and cost. Furthermore, the force during hoisting can be transferred to the reinforcing plate and ultimately borne by the entire sprocket box, avoiding the problem of the hoisting part being easily broken due to being subjected to force alone.

[0017] 3. The design of grooves and notches improves the structural strength of the sprocket box body and the reinforcing plate during the actual processing and casting of the sprocket box body;

[0018] 4. The groove design forms a reinforcing ridge on the hoisting part, effectively improving the structural strength of the hoisting part itself. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] A reinforced sprocket box, such as Figure 1 and Figure 2 As shown, the sprocket box body 1 is made of aluminum. The top of the sprocket box body 1 has a vertically recessed groove 2. A lifting part 3 is provided at the groove 2. There are two lifting parts 3 arranged in parallel. The two ends of the lifting parts 3 are fixed to the opposite side walls of the groove 2. In this embodiment, the lifting parts 3 are integrally cast with the sprocket box body 1. A horizontally penetrating lifting hole 4 is provided on the lifting part 3. Two lifting holes 4 are symmetrically arranged on one lifting part 3 to improve the stability of the lifting.

[0027] like Figures 1-3 As shown, the side wall of the hoisting part 3 has recessed grooves 5, which are distributed circumferentially around the hoisting hole 4. Reinforcing ridges 6 are formed between adjacent grooves 5, which effectively improves the structural strength of the hoisting part 3 itself.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, there are mounting cavities 7 on both sides of the sprocket box body 1. One mounting cavity 7 is used to connect to the motor of the electric hoist, and the other mounting cavity 7 is used to connect to the gearbox of the electric hoist. A reinforcing plate 8 is embedded in the sprocket box body 1 at the corresponding lifting part 3, and a reinforcing plate 9 is embedded at the bottom of the mounting cavities 7 on both sides of the sprocket box body 1. Both the reinforcing plate 8 and the reinforcing plate 9 are steel plates or iron plates, and the two ends of the reinforcing plate 8 are fixed to the reinforcing plates 9 on both sides to form a reinforced whole. In this embodiment, the reinforcing plate 8 is used to connect the motor of the electric hoist, and the other mounting cavity 7 is used to connect the gearbox of the electric hoist. The reinforcing plate 8 has inserts 10 at both ends, and slots 11 are provided on the reinforcing plate 9 to engage with the inserts 10, so as to realize the insertion and engagement of the reinforcing plate 9 and the reinforcing plate 8. This allows the reinforcing plate 9 and the reinforcing plate 8 to be manufactured separately and independently during production, reducing production difficulty and production cost. In other embodiments, the reinforcing plate 9 and the reinforcing plate 8 can also be integrally formed. In actual production, the reinforcing plate 8 and the reinforcing plate 9 are prefabricated, then placed in a mold, and the sprocket box body 1 is then cast in the mold to achieve the interlocking of the two.

[0029] The aluminum sprocket box body 1 is relatively lightweight. Combined with the embedded reinforcing plate 8 and the reinforcement plate 9, it effectively improves the overall structural strength of the sprocket box and the lifting part 3, effectively preventing the safety hazard of breakage due to insufficient structural strength at the lifting part. It well balances the weight and structural strength of the sprocket box and is suitable for large-tonnage electric hoists.

[0030] like Figure 4 As shown, multiple through slots 12 are provided on the reinforcing plate 9, and concave notches 13 are provided on the edge of the reinforcing plate 9. The notches 13 are arc-shaped and multiple notches 13 are distributed at intervals. The design of the through slots 12 and notches 13 improves the structural strength of the sprocket box body 1 and the reinforcing plate 9 when the sprocket box body 1 is actually processed and cast.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
