Abstract
Description
Technical Field
[0001] The utility model relates to the field of train unloading tool design, in particular to a train unloading safety following trolley device. Background Art
[0002] The lump ore in the raw material workshop of the blast furnace of the iron and steel plant is transported to the material storage yard by train. After the train stops at the stop, it is necessary for people to stand on the edge of the train car to cooperate with the workers below to open the unloading door of the car and then lift and fix it. Because there are excavators in the material storage yard to dig the lump ore in the car body and there are vehicles running above, there is no safety hanging point above the personnel working path. The workers who lift and fix the car door are more than 3 meters above the ground, and the total moving distance of the personnel on the edge of the train car is more than 150 meters. There are no protective measures and they are in a dangerous high-altitude working state. Occasionally, workers fall and get injured. Utility Model Content
[0003] The technical problem to be solved by the utility model is that high-altitude operations are highly dangerous and may cause injuries to workers.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a train unloading safety following trolley device, including a column, a track beam, a track body and a mobile trolley, the track beam is arranged on the column, the column is provided with multiple groups, the track beam is provided with an upper and lower group, the track body is arranged on the track beam, the track body is provided with an upper and lower group, the mobile trolley is slidably arranged on the track body, the mobile trolley includes an upper guide wheel, a lower guide wheel, a frame and wheels, the upper guide wheel is snap-fitted and slidably arranged on the upper side track body, the lower guide wheel is snap-fitted and slidably arranged on the lower side track body, the frame is arranged between the upper guide wheel and the lower guide wheel, and the wheel is arranged on the frame and slidably arranged on the lower guide wheel.
[0005] Furthermore, a cantilever is provided on the frame.
[0006] Furthermore, a lifting lug is provided on the cantilever.
[0007] Furthermore, the upper guide wheels are symmetrically provided in multiple groups, and the upper guide wheels are snap-fitted and slidably located on both sides of the upper track body.
[0008] Furthermore, the lower guide wheels are symmetrically provided in multiple groups, and the lower guide wheels are snap-fitted and slidably located on both sides of the lower track body.
[0009] Preferably, the cantilever is longer than 3.5 meters.
[0010] The beneficial effects achieved by the utility model using the above structure are as follows: a steel structure and two upper and lower track bodies are installed on the pillars beside the railway, and a lightweight mobile long cantilever trolley is installed, with the end hanging point located just above the path where people move. Considering safety, reliability and maintenance, the mobile trolley does not use electric drag, but uses human traction and following movement by operators. In order to reduce traction resistance, reduce the weight of the trolley, and facilitate manual dragging, the mobile trolley adopts a triangular light steel structure, which not only reduces weight but also ensures structural strength. The trolley moves by rolling friction to reduce movement resistance. The equipment runs smoothly, has low traction resistance, low failure rate, and is safe and reliable.

[0015] like Figure 1~Figure 3 As shown, the utility model is a train unloading safety following trolley device, including a column 1, a track beam 2, a track body 3 and a mobile trolley 4, the track beam 2 is arranged on the column 1, the column 1 is provided with multiple groups, the track beam 2 is provided with two upper and lower groups, the track body 3 is arranged on the track beam 2, the track body 3 is provided with two upper and lower groups, the mobile trolley 4 is slidably arranged on the track body 3, the mobile trolley 4 includes an upper guide wheel 5, a lower guide wheel 6, a frame 7 and a wheel 8, the upper guide wheel 5 is slidably arranged on the upper side track body 3, the lower guide wheel 6 is slidably arranged on the lower side track body 3, the frame 7 is arranged between the upper guide wheel 5 and the lower guide wheel 6, the wheel 8 is arranged on the frame 7 and slidably arranged on the lower guide wheel 6, due to site restrictions, there is a vehicle running above, and an excavator is below to excavate the block ore in the car body, and a fixed safety hanging point cannot be established above the working path of the operator. Therefore, a steel structure and two upper and lower track bodies are installed on the column beside the railway, and a lightweight mobile trolley is installed.
[0016] A cantilever 9 is provided on the frame 7, and a lifting lug 10 is provided on the cantilever 9. A plurality of upper guide wheels 5 are symmetrically provided, and the upper guide wheels 5 are slidably engaged and located on both sides of the upper track body 3. A plurality of lower guide wheels 6 are symmetrically provided, and the lower guide wheels 6 are slidably engaged and located on both sides of the lower track body 3.
[0017] During specific use: the track beam 2 and the track body 3 are arranged along the length direction of the train. The track body 3 is installed on the track beam 2, about 2 meters higher than the train box, supporting and providing a moving track and path for the mobile trolley 4. The frame body of the mobile trolley 4 and the long cantilever 9 are triangular structures, and the lifting lug 10 serves as a hanging point for a safety belt.
[0018] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
