Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment underground in coal mines, in particular to a blind rope maintenance platform on the top of a narrow tank in an auxiliary shaft. Background Art

[0002] According to the "Safety Regulations for Coal Mines", the lifting wire rope of the vertical shaft hoisting system must be inspected once a day. Since the blind rope section of the main lifting wire rope of the hoisting machine in the auxiliary shaft of Selian No. 2 Mine needs to be inspected at the wellhead, each time the wide and narrow tank blind rope section is inspected, a springboard must be laid on the wellhead frame beam. Due to the large span of the shaft and high-altitude operations, there are major safety hazards in the process of erecting and dismantling the blind rope springboard platform. At least 5 skilled maintenance workers are required to cooperate with each other each time. It takes at least 3 hours to complete the inspection of the entire blind rope section, which is time-consuming and labor-intensive. The total maintenance time is 4 hours, which seriously affects the efficiency of maintenance and the safety of personnel. Utility Model Content

[0015] Figure 2 It is a top view of an embodiment of the utility model. DETAILED DESCRIPTION

[0016] In order to facilitate those skilled in the art to understand the technical solution of the utility model, the technical solution of the utility model is further explained in conjunction with the drawings in the specification.

[0017] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0018] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically limited.

[0019] See also Figure 1 and Figure 2This embodiment discloses a blind rope maintenance platform for the tank top of the auxiliary shaft wide and narrow tank, including a fixed beam 1, a telescopic claw 2, and a springboard platform 3. Two sets of fixed beams 1 are arranged in parallel on the tank top of the auxiliary shaft wide and narrow tank 4 by bolts, so that the fixed beams 1 can be disassembled from the tank top of the auxiliary shaft wide and narrow tank 4. In this embodiment, the fixed beams 1 are channel steels. A springboard platform 3 is arranged between the two sets of fixed beams 1 for maintenance personnel to walk around for maintenance.

[0020] The end of each group of fixed beams 1 is sleeved with a telescopic claw 2 that can slide and overlap on the auxiliary shaft wellhead beam 5. The telescopic claw 2 is provided with a mounting hole 21 that can be sleeved on the positioning pin 6 on the auxiliary shaft wellhead beam 5. When the telescopic claw 2 slides out from the fixed beam 1 and moves toward the auxiliary shaft wellhead beam 5, and the mounting hole 21 moves to the top of the positioning pin 6, the auxiliary shaft width and narrow tank 4 is lowered, so that the telescopic claw 2 is spanned on the auxiliary shaft wellhead beam 5 and the positioning pin 6 is sleeved on the mounting hole 21, preventing the telescopic claw 2 from moving, ensuring that the fixed beam 1 can be stably fixed on the auxiliary shaft wellhead beam 5, thereby ensuring the safety of the maintenance personnel on the gangway platform 3.

[0021] Specifically, when replacing the wide and narrow tank suspension cylinder, the maintenance platform is used for replacement. Compared with the previous laying and removal of the springboard platform 3, the springboard platform 3 on the maintenance platform is set on the top of the wide and narrow tank 4 in the auxiliary shaft. There is no need to lay and remove the springboard platform 3 during maintenance, so that maintenance personnel can replace it in a short time, improving maintenance efficiency. And when the wide and narrow tank lifting rope jumps, the maintenance platform can be used to operate, reducing safety hazards, effectively increasing the speed of jumping rope, and improving maintenance efficiency. In addition, the maintenance platform can also be deployed on the frame beam at any location in the shaft, effectively improving the maintenance quality.

[0022] Furthermore, the springboard platform 3 is a foldable platform.

[0023] Furthermore, a guardrail 7 close to the springboard platform 3 is provided between the two groups of fixed beams 1 .

[0024] The working principle of this embodiment is: remove the arc-shaped canopy of the auxiliary shaft width and narrow tank 4, change it into a straight canopy surface, use 140# channel steel, 50# angle iron, and 5mm steel plate to process a "well"-shaped platform, and then install and fix the maintenance platform above the safety canopy. Specifically, first stop the top of the auxiliary shaft width and narrow tank 4 to the parallel position of the wellhead cradle, and the personnel enter the tank top, lower the auxiliary shaft width and narrow tank 4 to the wellhead sleeve beam position, and the personnel climb the tank top ladder to the top of the tank cap, fix the safety belt to the rooting fixed point, remove the bolts connecting the fixed beam 1 and the tank top of the auxiliary shaft width and narrow tank 4, and then pull out the telescopic claw 2 at the end of the fixed beam 1, so that the installation hole 21 moves to the top of the positioning pin 6, and then lower the auxiliary shaft width and narrow tank 4 until the telescopic claw 2 is set on the auxiliary shaft wellhead beam 5 and the positioning pin 6 is set on the installation hole 21, and the erection of the maintenance platform and the sleeve beam is completed. Finally, the personnel go up to the springboard platform 3 and slowly lower the auxiliary shaft width and narrow tank 4. The vehicle stops when the hanging device of the auxiliary shaft width and narrow tank 4 is lowered to 0.5m below the springboard platform 3. The personnel unfold the folded springboard platform 3 and stand on the springboard platform 3 to start inspecting the blind rope section of the main lifting wire rope.
