Description

Technical Field

[0001] This utility model belongs to the technical field of cable trough installation for transport aircraft, and particularly relates to a lifting and installation device for cable troughs for transport aircraft. Background Technology

[0002] In coal mining, to transport the coal cut from the roadway by mining equipment such as fully mechanized mining machines, it is currently necessary to install conveyor systems, mostly scraper conveyors, within the mining roadways. The main structure of a scraper conveyor includes a chute where the coal is transported. Toothed rails are installed on the chute, and these rails form part of the scraper conveyor system.

[0003] Meanwhile, the scraper conveyor also needs to install heavy cable trays, which provide a foundation for the subsequent cable installation. Due to the considerable weight of the cable trays and the fact that the installation takes place in narrow tunnels, the current installation method, to save labor, often involves using a hoist to lift the cable trays before installation.

[0004] However, in actual work, it was found that because the cable trays needed to be installed along the length of the chute, the lifting guardrails needed to be moved and reinstalled after each section was completed. The entire construction process was very cumbersome and not very safe.

[0005] Meanwhile, during the hoisting process, the cable trough plate material needs to be pushed to the installation position after being lifted by the hoist. Although the cable trough plate is easy to push when it is suspended, it is relatively dangerous during the operation. This is because once the cable trough plate is pushed, if the operator fails to hold the cable trough plate stably, the loose cable trough plate will swing in the suspended state. If the heavy cable trough plate hits personnel or equipment during the swing, it will cause a serious safety accident.

[0006] Therefore, adopting a cable tray installation device that is efficient, labor-saving, and safe is very important for improving the installation efficiency and safety of cable trays on scraper conveyors. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a lifting and installation device for a transport vehicle cable trough.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A lifting and installation device for a conveyor cable trough includes a lifting mechanism that travels on the scraper conveyor trough.

[0010] The hoisting mechanism includes a boom, which is hinged to a rotating support structure. The rotating support structure includes a rotating support hinged to the boom. A base plate is fixedly connected to the bottom of the rotating support, and a rotating part is integrally formed at the bottom of the base plate. A hinged support is fixedly connected to the rotating part, and a lifting structure for lifting the boom is hinged to the hinged support.

[0011] The rotating part is rotatably connected to a bottom support arm, and a rotating push structure for pushing the rotating support structure to rotate is installed on the bottom support arm;

[0012] The scraper conveyor chute is equipped with a toothed rail, and the bottom support arm is fixedly installed with a sliding bracket that slides on the toothed rail; the hoisting mechanism travels on the toothed rail via a creeping mechanism.

[0013] Preferably, the rotating bracket is welded obliquely to the base plate;

[0014] Hinged guard plates are fixedly connected to the side walls on both sides of the tail of the boom, and the upper end of the rotating bracket is hinged to the tail of the hinged guard plates.

[0015] Preferably, the lifting structure includes a lifting hydraulic cylinder, and the piston rod of the lifting hydraulic cylinder is hinged to the front end of the hinge guard plate;

[0016] The cylinder of the lifting hydraulic cylinder is hinged to the hinge bracket.

[0017] Preferably, the rotary pushing structure includes a rotary pushing hydraulic cylinder, the cylinder barrel of which is hinged to the outer end of the bottom support arm;

[0018] A pair of lugs are welded to the side wall of the rotating bracket, and the piston rod of the rotating hydraulic cylinder is hinged between the lugs.

[0019] During the process of rotating and pushing the hydraulic cylinder, the rotating part rotates relative to the bottom support arm.

[0020] Preferably, the outer end of the bottom support arm is fixedly connected to a vertical hinge shaft that is hinged to the cylinder of the rotary hydraulic cylinder.

[0021] Preferably, the creeping mechanism includes a horizontally pushing hydraulic cylinder mounted on a sliding bracket;

[0022] It also includes a movable support that engages with the gear rail, wherein the piston rod pin of the horizontally pushing hydraulic cylinder is fixed to the side of the movable support.

[0023] Preferably, a plurality of spaced toothed plates are fixedly connected to the toothed rail;

[0024] The movable support has a fulcrum rod inserted into the pin. During the sliding process of the sliding bracket, which is pushed by the horizontal hydraulic cylinder, the fulcrum rod abuts against the toothed plate.

[0025] Preferably, a pair of pin lugs are fixedly connected to the outer wall of the movable support, and a pin hole is opened at the end of the piston rod of the horizontal push hydraulic cylinder. A pin shaft is inserted into the pin lug and fixed in the pin hole.

[0026] Preferably, the longitudinal cross-sectional shape of the sliding bracket is U-shaped, and the sliding bracket is limited to sliding on the toothed rail.

[0027] Preferably, the suspension end of the boom is welded with a lifting lug.

[0028] This utility model has the following beneficial effects:

[0029] 1. The rotating support structure, formed by the rotating bracket, base plate, rotating part, and bottom support arm lock, has high overall structural stability, providing more stable rotational movement for the boom and suspended cable trough. Specifically, under the push of the rotating hydraulic cylinder, the entire rotating support structure can swing to the installation position in a stable manner.

[0030] The stability of the support structure increases operational safety. Furthermore, the stability of the support means that the cable tray swings less after being suspended, which further enhances operational safety and makes it easier for operators to accurately lower the cable tray into the installation position.

[0031] Meanwhile, the entire movement process, from lifting the cable tray to rotating and swinging it to the installation position, requires no manual intervention, further increasing efficiency and enhancing operational safety.

[0032] 2. During operation, the horizontal hydraulic cylinder first pushes the movable support in the opposite direction until the fulcrum rod contacts the toothed plate. Then, the horizontal hydraulic cylinder pushes in the opposite direction, moving the entire lifting mechanism forward to the installation position. When the lifting mechanism needs to be moved forward again, the operator pulls the fulcrum rod off the movable support. As the horizontal hydraulic cylinder retracts the plunger rod, it pulls the movable support to slide onto the next toothed plate position on the toothed rail. The operator then inserts the fulcrum rod back into the movable support and, following the same procedure, moves the entire device forward again using the horizontal hydraulic cylinder.

[0033] 3. The hoisting device disclosed in this utility model enables the suspension, rotation, and self-movement of cable troughs during installation on chutes. This not only greatly reduces the labor intensity of installation work but, more importantly, increases the safety of installation operations and reduces the probability of accidents.

[0043] Example 1

[0044] like Figure 1-4 As shown, a lifting and installation device for a conveyor cable trough includes a lifting mechanism 3 that travels on the scraper conveyor chute 1.

[0045] The specific structure of hoisting mechanism 3 is as follows:

[0046] The hoisting mechanism 3 includes a boom 31 (the boom 31 is a prior art disclosed for use with the same working method as the existing boom 31, with lifting lugs welded to the suspension end of the boom 31, and during operation, steel ropes are fixed to the lifting lugs, and the cable tray is fixed by steel ropes).

[0047] To enable the safe, flexible, and labor-saving rotation and repositioning of the hoisted cable trough to the installation position during the hoisting process, this utility model makes the following improvements:

[0048] The boom 31 is hinged to a rotating support structure 33, which includes a rotating support 331 hinged to the boom 31 (the hinge method is as follows: hinge guard plates are fixedly connected to the left and right side walls of the tail of the boom 31 respectively, the bottom of the hinge guard plate protrudes from the bottom surface of the boom 31, and correspondingly, the upper end of the rotating support 331 is hinged to the tail of the hinge guard plate by a pin).

[0049] Meanwhile, the bottom of the rotating bracket 331 is fixedly connected to the base plate 332 (specifically, the rotating bracket 331 is inclined and welded to the base plate 332, with the inclination direction being rearward, which allows the boom 31 to be tilted up to the maximum extent).

[0050] Meanwhile, the bottom of the base plate 332 is integrally formed with a rotating part 3321; the rear side wall of the rotating part 3321 is fixedly connected with a hinge bracket 334 (to... Figure 3 (The orientation shown is for reference only). A pair of hinged parts are integrally formed on the hinged bracket 334. At the same time, the lifting structure of the lifting boom 31 is hinged on the hinged bracket 334. Specifically, the lifting structure includes a lifting hydraulic cylinder 32. The plunger rod of the lifting hydraulic cylinder 32 is hinged to the front end of the hinge guard plate 311 (similarly, the front end of the hinge guard plate 311 is hinged to the plunger rod of the lifting hydraulic cylinder 32 by a pin hinge. Correspondingly, the top of the plunger rod is fixedly connected to a hinge tongue).

[0051] Similarly, the bottom of the cylinder of the lifting hydraulic cylinder 32 is fixedly connected with a hinge tongue, which is hinged between a pair of hinge parts integrally formed on the hinge bracket by a pin.

[0052] During operation, once the cable trough is secured by steel ropes, the boom 31 is raised under the action of the lifting hydraulic cylinder 32. During the raising process, the boom 31 rotates relative to the rotating bracket 331, and after being raised, it lifts the cable trough.

[0053] Meanwhile, the rotating part 3321 is rotatably connected to a bottom support arm (the rotatable connection method is as follows: according to the existing rotatable connection method, a rotating shaft is fixedly connected to the top of the bottom support arm 335, and the rotating shaft is rotatably connected to the rotating part 3321. The method is as follows: the same as the existing rotatable connection method, a mounting groove is opened at the bottom of the rotating part 3321, and the bearing is fixedly installed in the mounting groove, and the rotating shaft is rotatably connected to the bearing).

[0054] Meanwhile, in order to synchronously rotate the boom 31 and the suspended cable tray to the installation position close to the cable tray, a rotating push structure is installed on the bottom support arm 335 to push the rotating bracket 331 structure 33 to rotate.

[0055] Specifically, the rotary push structure includes a rotary push hydraulic cylinder 34, the cylinder of which is hingedly mounted on the outer end of the bottom support arm 335 (specifically, the outer end of the bottom support arm 335 is fixedly connected to a vertical hinge shaft 341 hinged to the cylinder of the rotary push hydraulic cylinder 34, and correspondingly, a hinge ear plate is fixedly connected to the cylinder).

[0056] Meanwhile, a pair of lugs 3311 are welded to the lower end of the side wall of the rotating bracket 331, and the piston rod of the rotating hydraulic cylinder 34 is hinged between the lugs 3311 (the hinge method is the same as the piston rod hinge method of the hydraulic cylinder mentioned above).

[0057] When the hoisted cable tray needs to be rotated to the installation position, the rotating support 331 and the rotating part 3321 rotate relative to the bottom support arm 335 under the push of the rotating hydraulic cylinder 34, and the hoisted cable tray rotates synchronously at this time.

[0058] The advantages of the above structural design are:

[0059] Firstly, the stability of the rotating bracket 331 structure 33, formed by the aforementioned rotating bracket 331, base plate 332, rotating part 3321, and bottom support arm 335, provides a more stable rotational motion for the boom 31 and the suspended cable trough. That is, under the push of the rotating hydraulic cylinder 34, the entire rotating bracket 331 structure 33 can be stably rotated to the installation position.

[0060] The stability of the support structure increases operational safety. Furthermore, the stability of the support means that the cable tray swings less after being suspended, which further enhances operational safety and makes it easier for operators to accurately lower the cable tray into the installation position.

[0061] Meanwhile, the entire movement process, from lifting the cable tray to rotating and swinging it to the installation position, requires no manual intervention, further increasing efficiency and enhancing operational safety.

[0062] Example 2

[0063] like Figure 1-4 As shown, this embodiment is based on the structure of embodiment 1. A toothed rail 2 is installed on the existing scraper conveyor chute 1 (the toothed rail 2 is an inherent part of the scraper conveyor chute 1, used for the movement of subsequent coal mining equipment, and has the same structure as the toothed rail 2 on the existing chute 1; several spaced toothed plates 21 are fixedly connected to the toothed rail 2). This utility model cleverly utilizes the toothed rail 2 built into the scraper conveyor chute 1 to enable the entire device to be moved to the next installation location after one cable trough plate has been hoisted and installed. Through autonomous movement, it achieves safer and more labor-saving movement.

[0064] Specifically, a sliding bracket 36 is fixedly installed on the bottom of the bottom support arm 335 and slides on the gear rail 2 (the bottom of the bottom support arm 335 and the sliding bracket 36 are welded together by a pad steel 3351). Specifically, the longitudinal cross-sectional shape of the sliding bracket 36 is a U-shaped structure, and the sliding bracket 36 is limited to slide on the gear rail 2.

[0065] Meanwhile, the hoisting mechanism 3 travels on the geared rail 2 via a creeping mechanism. Specifically, the creeping mechanism includes a horizontally pushing hydraulic cylinder 35 mounted on a sliding bracket 36; the installation method is as follows: the cylinder of the horizontally pushing hydraulic cylinder 35 is movably mounted on the sliding bracket 36 (a pair of fixed lugs are welded to the outer wall of the sliding bracket 36, and similarly, a pin plate is welded to the cylinder, and the hinge tongue is pinned to the hinge lugs by a pin shaft).

[0066] Similarly, it also includes a movable support 351 that mates with the gear rail 2 (the movable support 351 is also a U-shaped structure, which limits sliding on the gear rail 2), and the plunger rod of the horizontally pushing hydraulic cylinder 35 is pinned to the side of the movable support 351. Specifically, a pair of pin lugs are welded to the outer wall of the movable support 351, and the plunger rod of the horizontally pushing hydraulic cylinder 35 has a pin hole at its end. A pin is inserted into the pin lug and is pinned to the pin hole.

[0067] According to the existing anchoring method, the movable support 351 has a fulcrum rod at the midpoint (the movable support 351 has a socket A at the midpoint to cooperate with the fulcrum rod), and the fulcrum rod is inserted through the socket A.

[0068] Meanwhile, during the sliding process of the sliding bracket 36 being pushed by the horizontal hydraulic cylinder 35, the fulcrum rod (not shown in the figure) abuts against the toothed plate 21.

[0069] During operation, the horizontally driven hydraulic cylinder 35 first pushes the movable support 351 to slide in the opposite direction until the fulcrum rod abuts against the toothed plate 21. At this point, the horizontally driven hydraulic cylinder 35 pushes in the opposite direction, and the entire lifting mechanism 3 moves forward to the installation position. When it is necessary to move the lifting mechanism 3 forward again, the operator pulls the fulcrum rod out of the movable support 351. As the horizontally driven hydraulic cylinder 35 retracts the plunger rod into the cylinder, it pulls the movable support 351 to slide onto the next toothed plate 21 on the toothed rail 2. Then, the operator inserts the fulcrum rod back into the movable support 351 and moves the entire device forward again by driving it with the horizontally driven hydraulic cylinder 35 in the same manner.

[0070] The above structure enables the entire device to move using a creeping motion. Similarly, it allows for forward movement after the cable tray is hoisted.

[0071] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
