Description

Technical Field

[0001] The utility model belongs to the technical field of coal mining, and in particular relates to an escape device for a transfer machine. Background Art

[0002] The full name of the transfer machine is the scraper transfer machine for the chute. It is a bridge-type scraper conveyor installed in the section transport level tunnel at the exit of the working face of the mine. The transfer machine is the main equipment for comprehensive mining and transportation in coal mines. When the transfer machine is working, one end is connected to the conveyor of the working face, and the other end is connected to the tail of the belt conveyor. Its role in the three-machine matching of large-scale comprehensive mining technology is to transfer the coal transported by the scraper on the mining face to the belt conveyor after the bottom plate of the tunnel is raised.

[0003] In the prior art, in order to prevent coal from spilling out of the middle trough of the suspended section, a cover plate is set on the top of the middle trough of the suspended section. Since the middle trough of the landing section is not provided with a cover plate, if a special situation occurs, the staff accidentally falls into the middle trough of the landing section and is easily brought into the middle trough of the suspended section by the coal flow. The transfer machine includes multiple sections of the middle trough of the suspended section connected in sequence, and the structure is relatively long. The direction of the coal flow is from the tail of the transfer machine to the head. It is difficult for the staff to go back to the middle trough of the landing section against the direction of the coal flow. Since the middle trough of the suspended section is provided with a cover plate, the staff cannot escape directly through the middle trough of the suspended section. This results in that once the staff is brought into the middle trough of the suspended section, it will be difficult to escape quickly.

[0004] Based on this, the existing technology needs to be further developed. Utility Model Content

[0005] In view of various deficiencies in the prior art, a transfer machine escape device is now proposed to solve the technical problem in the prior art that workers are brought into the middle groove of the suspended section of the transfer machine and are difficult to escape.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0022] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0023] According to the embodiment of the utility model, a transfer machine escape device is provided. Figures 1 to 3 A transfer machine escape device comprises: an escape opening 2, which is arranged on a cover plate 1, and the cover plate 1 is arranged above the middle groove of the suspended section of the transfer machine; an escape ladder 3, the first end of the escape ladder 3 is located outside the middle groove of the suspended section and connected to the outside, and the second end of the escape ladder 3 extends to the inside of the middle groove of the suspended section.

[0024] It should be noted that, on the one hand, if a special situation occurs and a worker is accidentally brought into the middle trough of the suspended section by the coal flow, he or she can use the escape ladder 3 to climb out of the escape opening 2 and escape quickly; on the other hand, if the scraper is stuck, affecting the operation of the transfer machine, and it is necessary to enter the interior of the middle trough of the suspended section for maintenance, the escape ladder 3 can also be used to enter the interior of the middle trough of the suspended section from the cover plate 1.

[0025] Preferably, since the transfer machine includes several sections of suspended middle troughs, once the staff realizes that they are caught in the coal flow, they will immediately look for an escape hole 2 to escape. Therefore, near the head of the transfer machine, an escape hole 2 and an escape ladder 3 are set every 1-2 sections of the suspended middle trough, so that the staff can quickly escape if they are accidentally brought into the suspended middle trough by the coal flow; and near the tail of the transfer machine, the interval between two adjacent escape holes 2 can be appropriately increased. Because near the tail of the transfer machine, the probability of using the escape hole 2 for escape is relatively small, and it is mainly used for maintenance. One escape hole 2 can be used to enter several adjacent suspended middle troughs for maintenance, avoiding waste caused by too many escape holes 2 and escape ladders 3.

[0026] Specifically, a plurality of waist holes 4 are formed on the cover plate 1, and the fixing parts pass through the waist holes 4 to connect the cover plate 1 and the middle groove of the suspended section.

[0028] It should be noted that, due to the need for maintenance of the transfer machine, workers are often required to walk on the cover plate 1. In order to prevent workers from accidentally falling into the middle groove of the suspended section through the escape opening 2, a guardrail 6 is arranged around the escape opening 2. At the same time, the guardrail 6 also provides a reliable connection point for the escape ladder 3.

[0029] Preferably, a passage 9 for workers to pass through is formed between the guardrail 6 and the edge of the cover plate 1, so that the workers can quickly pass through the cover plate 1 with the escape hatch 2 to reach the location that needs maintenance.

[0030] In the transfer machine escape device of this embodiment, the guardrail 6 includes a plurality of staggered cross bars 7 and a plurality of vertical bars 8 connecting the plurality of cross bars 7 , and the first end of the escape ladder 3 is connected to two vertical bars 8 adjacent to the guardrail 6 .

[0031] Specifically, the cross bar 7 is made of round steel pipe, the vertical poles 8 located at the corners of the guardrail 6 are made of angle steel, and the vertical pole 8 located in the middle of the side of the guardrail 6 is made of round steel pipe. The surface of the round steel pipe is smooth and has no edges and corners, reducing the risk of injury to workers.

[0032] In the transfer machine escape device of this embodiment, the vertical pole 8 made of circular steel pipe includes several sections, and the end of each vertical pole 8 connected to the cross bar 7 is gas cut into an arc, and the arc surface of the arc fits the surface of the cross bar 7.

[0033] It should be noted that the connection between the circular steel pipes is welded with fillet welds, and the corners of the guardrail 6 are welded with angle steels, which ensures the connection stability of the guardrail 6 and also has aesthetics.

[0034] In the transfer machine escape device of the present embodiment, the escape ladder 3 is an escape ladder 3, and a ladder box 5 is provided on the lower surface of the cover plate 1. The first end of the escape ladder 3 is connected to the guardrail 6. When the escape ladder 3 is in an idle state, the second end of the escape ladder 3 is placed inside the ladder box 5. When the escape ladder 3 is needed, the second end of the escape ladder 3 is taken out of the ladder box 5, and the escape ladder 3 is used to enter the middle groove of the suspended section or climb out of the middle groove of the suspended section.

[0035] It should be noted that the escape ladder 3 is easy to store, and the ladder box 5 for storing the escape ladder 3 is arranged on the cover plate 1, which is not easily affected by the coal flow and is convenient to use at any time.

[0036] In the transfer machine escape device of this embodiment, the ladder box 5 is connected to the side of the cover plate 1 close to the middle groove of the suspended section, and the opening of the ladder box 5 is arranged close to the escape opening 2 to facilitate access to the escape ladder 3.

[0037] Preferably, the opening of the ladder box 5 is flush with one side of the escape opening 2 to prevent the ladder box 5 from extending into the escape opening 2 and causing interference, thereby affecting the staff's entry and exit of the middle groove of the suspended section through the escape opening 2.

[0038] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention.
