Description

Hydraulic support disassembling system

Technical Field

The utility model relates to an equipment disassembling technical field especially relates to a hydraulic support system of disassembling.

Background

The hydraulic support is support equipment used for a coal mining working face of a coal mine, is usually used in a set of dozens to hundred, and needs to be lifted for maintenance to maintain support capacity after being used for a certain time. The most important step during maintenance is the disassembly work of the hydraulic support, and the most time-consuming and labor-consuming disassembly process is the disassembly of the hinge pin shaft, such as the disassembly of the hinge pin shaft between the top beam and the shield beam, the disassembly of the hinge pin shaft between the connecting rod and the base and the like. Based on the weight of the hydraulic support, the weight mainly comes from each structural part, so that the weight of single structural parts such as a top beam and a shield beam is generally from several tons to more than ten tons, the hinge pin shaft is positioned at the hinge joint of the heavy structural part, the hinge pin shaft is obviously extruded by the structural part and the like, and the disassembly resistance is very large. Therefore, when the hinge pin shaft is disassembled at present, the top beam or the shield beam and the like are properly lifted by means of equipment such as a travelling crane and the like, so that the condition that the hinge pin shaft is pressed is relieved, and the disassembling resistance is reduced.

However, due to the difference of personal experience and operation capability, the action precision of equipment such as a travelling crane is also different, and in the actual pin disassembling process, it is difficult to lift a top beam, a shield beam and the like to a degree that the pin pulling resistance is just ideal, so in the whole disassembling process, the travelling crane is frequently required to be frequently clicked (i.e. a control button on a remote control handle is clicked), and the pin pulling force is matched to complete the disassembling work of the hinge pin shaft. Specifically, when the hinge pin is not extruded by a structural member or is extruded by the structural member to a small extent, namely in an ideal state, the hinge pin is easy to pull out, and when the hinge pin is extruded by the structural member upwards or downwards obviously, the pin pulling resistance is large, and the pin pulling is difficult; when the hinge pin shaft is upwards extruded by the structural part, the lifting force of the trolley is large, the trolley is inching to be downwards placed, and the pin shaft can be outwards pulled out by a certain length in an ideal state in the placing process; because the fit clearance between the hinge pin shaft and the pin hole is small, the lifting and releasing actions are obvious no matter how the traveling crane is inching, and in addition, the time length of the operator inching the traveling crane each time has an error, the structural part is easy to change into a state of downwards extruding the hinge pin shaft, namely the lifting force is small; then the trolley is driven to lift, and the hinged pin shaft can be pulled out by a certain length again through an ideal state in the lifting process; the bicycle is frequently inching to carry out lifting and dropping actions in a reciprocating mode, and the hinge pin shaft can be pulled out for a section at the moment when the ideal state is reached in most lifting or dropping processes, so that the hinge pin shaft can be pulled out completely.

Although the disassembling mode of the manually-matched travelling crane can achieve the disassembling purpose, the mode has very high requirements on experiences of manually lifting the structural part, jogging the travelling crane in the disassembling process and the like, the manually-operated travelling crane is easy to fatigue, and the efficiency is still low; in addition, when the vehicle is driven by frequent inching, the load of the driving circuit elements and the like is large, and the driving fault is easily caused. Therefore, the disassembly method needs to be improved to improve the current situation.

Detailed Description

The invention is further explained below by referring to the drawings and examples. In the following detailed description, exemplary embodiments of the invention are described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1 and fig. 2 together, the hydraulic support dismantling system comprises a frame body 1, wherein a dismantling position is arranged in the frame body 1, a weighing platform 2 is arranged at the dismantling position in the frame body 1, and the weighing platform 2 is used for bearing a hydraulic support 9. The weighing platform 2 is connected with a weight sensor 21, and the weight sensor 21 is used for detecting the weight of the hydraulic support 9 on the weighing platform 2 in real time. Conventionally, the weight sensor 21 includes a load cell.

The frame body 1 is provided with a lifting device 3 above the disassembling position, and the lifting device 3 is used for lifting a structural part of the hydraulic support 9. After the hydraulic support 9 is placed on the weighing platform 2, the lifting device 3 can lift the structural part, the weight sensor 21 can sense the change of the whole weight of the hydraulic support 9, and the change is the strength of the lifting device 3 for lifting the structural part. Thus, the lifting degree of the lifting device 3 can be intuitively reflected by the weight sensor 21, so that the lifting device 3 can be easily controlled at a position where the hinge pin 96 is easily disassembled.

Preferably, the weight sensor 21 is in signal connection with a control device, an output end of the control device is in signal connection with the lifting device 3, and the lifting device 3 can reach a required position once by automatic control of the control device, so that the disassembly resistance of the hinge pin shaft 96 can be quickly relieved, and the disassembly efficiency is naturally improved.

In actual use, the difference of the weight change can be preset according to the weight of the structural members such as the top beam 91 or the shield beam 92; in the process of lifting the first hydraulic support 9, the weight of the hydraulic support 9 lifted by the lifting device 3 is directly reduced by the difference. According to the state of the hinge pin 96, the lifting device 3 is manually operated until the hinge pin 96 is in the ideal disassembly state, and the difference is obtained. Even if a plurality of operations including putting and lifting are required in the process, the difference can be easily obtained according to the visual reflection of the weight sensor 21.

The above-described method of use is exemplified below. If the weight of the hydraulic support 9 is 10t and the top beam 91 is 2t, the difference is set to be 2t before use. When the lifting device 3 lifts the difference value of 2t, the weight sensor 21 displays the weight of 8 t. If the hinge pin 96 is in the upward pressed state at this time, it indicates that the lifting degree of the lifting device 3 is too large, and at this time, the lifting device 3 is lowered downward and is stopped immediately after passing the ideal state of detachment, and it is assumed that the weight sensor 21 senses 8.116t after stopping. After that, the lifting device 3 is lifted upwards, and is also stopped immediately after crossing the ideal disassembly state, the hinge pin 96 returns to the upward extrusion state, and if the weight sensor 21 displays 8.156t at this time, it is easy to roughly obtain, when the hinge pin 96 is in the ideal disassembly state, the total weight of the hydraulic bracket 9 is about (8.116 + 8.156)/2 =8.136t, and the corresponding difference value should be 10-8.136=1.864t; the determination of the ideal disassembly state can be visually displayed in a pin pulling force application manner through real-time cooperation, and the ideal disassembly state is obtained at the moment when the hinge pin 96 can be pulled. In addition, the more accurate difference value can be obtained through the three-time or even multiple lifting operation, the previously set difference value is modified into the measured accurate difference value, and then after the subsequent hydraulic support 9 is placed on the weighing platform 2, the difference value can be quickly lifted and carried through the lifting device 3, so that the hinge pin shaft 96 can quickly reach an ideal state of easy disassembly.
