[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-6 As shown, this embodiment proposes a safety protection device for a monorail crane, including a protective frame 1 and a hanger 3 assembled on the top of the protective frame 1. A box 2 is fixedly installed inside the protective frame 1. An observation screen 205 is fixedly installed on the front of the box 2. A traction seat 4 is fixedly installed on the back of the protective frame 1 through a mounting base 401. A buffer spring 403 is fixedly installed on the front side inside the traction seat 4. A buffer plate 402 is fixedly installed on the back of the buffer spring 403.

[0027] In use, the box 2 allows workers to easily ride and operate the monorail. Inside the box 2, workers can observe the monorail's movement through the observation mesh 205. The protective frame 1 is fixedly installed inside the box 2, reinforcing the exterior of the box 2 and preventing or reducing dents and deformations during collisions. This enhances the overall strength of the box 2 and increases the safety of workers operating the monorail from inside. The traction seat 4 facilitates connection between the monorail and external transport carriages, allowing workers to easily traction the carriages. The buffer plate 402 and buffer spring 403 work together to elastically buffer and dissipate the impact of the carriages during braking, preventing excessive impact from the rear carriages and damage to the traction seat 4.

[0028] Example 2

[0029] Based on Example 1, such as Figure 1-4 As shown, a fixed seat 302 is fixedly installed at the bottom of the hanger 3 and installed on the top of the protective frame 1. The fixed seat 302 and the protective frame 1 are fixedly connected by a connecting plate 103. A track wheel 301 is rotatably installed on the top of the hanger 3. A fall arrestor plate 5 is fixedly installed inside the hanger 3 by a mounting pin 501. A brake plate 503 is fixedly installed at the bottom of the fall arrestor plate 5 by a fixing rod 502.

[0030] In use, the hanger 3 is fitted onto the outside of the track, and the track wheel 301 rotatably mounted on the hanger 3 rolls in contact with the track. Thus, the protective frame 1 and the box 2 can be suspended and installed below the track through the hanger 3 and the track wheel 301. The anti-fall plate 5 is fixedly installed inside the hanger 3 by the mounting pin 501. The anti-fall plate 5 is locked inside the track. When the track wheel 301 derails on the track, the anti-fall plate 5 can contact the track and support the hanger 3, thus preventing the monorail from falling when it derails, avoiding the safety accident of falling when the monorail derails, and increasing the safety of the monorail during use. The bottom of the anti-fall plate 5 is fixedly installed with a brake plate 503 by the fixing rod 502. The brake plate 503 can decelerate when the anti-fall plate 5 contacts the track support, thus quickly stopping the monorail and ensuring the safety of the monorail when it derails.

[0031] like Figure 4 As shown, a reinforcing plate 101 is fixedly installed at the bottom of the protective frame 1, and an anti-collision plate 102 is fixedly installed at the bottom of the reinforcing plate 101.

[0032] When in use, the reinforcing plate 101 can connect and reinforce the bottom of the protective frame 1, and the anti-collision plate 102 can protect the bottom of the protective frame 1 from collision, thus preventing damage to the bottom of the protective frame 1 caused by bumps and ensuring the safety of the protective frame 1 during operation.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, door panels 201 are movably installed on both sides of the box body 2, and handrails 202 are fixedly installed on the front side of both sides of the box body 2.

[0034] When in use, the door panel 201 can close both sides of the box 2, thereby ensuring the safety of the staff when operating inside the box 2. The handrail 202 is convenient for staff to hold and support when entering and exiting the box 2, ensuring the stability of the staff when entering and exiting the box 2.

[0035] like Figure 1 As shown, a lighting lamp 203 is fixedly installed on the front of the box 2, and a protective railing 204 is fixedly installed on the outside of the lighting lamp 203.

[0036] When in use, the lighting lamp 203 can provide illumination from the front when the monorail is moving, making it convenient for staff to observe and understand the front when operating the box 2. The guardrail 204 can protect the front of the lighting lamp 203, preventing damage to the lighting lamp 203 caused by collisions and bumps.

[0037] like Figure 1-3 As shown, reinforcing angle plates 303 are fixedly installed on the outer side of the hanger 3, and the bottom of the reinforcing angle plates 303 is fixedly connected to the top of the fixing seat 302.

[0038] When in use, the reinforcing angle plate 303 can reinforce the connection between the hanger 3 and the fixed seat 302, preventing deformation and breakage of the work vehicle between the hanger 3 and the reinforcing angle plate 303, and increasing the stability of the hanger 3 during operation.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, a rubber plate 104 is fixedly installed on the front side of the protective frame 1.

[0040] When in use, the rubber plate 104 can provide flexible protection and buffer when the front of the protective frame 1 is involved in a collision, reducing the damage caused to the protective frame 1 and the box 2 by the frontal collision, and ensuring the safety of the front of the monorail.

[0041] Working principle: The operator can control the monorail from inside the box 2. The protective frame 1 protects the exterior of the box 2, preventing or reducing dents and deformations caused by collisions. The protective frame 1 also increases the stability of the box 2 during suspension operations. The traction seat 4 facilitates the connection between the monorail and the transport car behind it, enabling the monorail to traction the transport car. The buffer spring 403 and buffer plate 402 provide elastic buffering and stress relief against the impact force on the transport car when the monorail brakes. The hanger 3 and track wheel 301 allow for suspension operations of the monorail. The anti-fall plate 5 prevents the monorail from falling when the track wheel 301 derails, ensuring the safety of the monorail in the event of derailment.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
