Description

Technical Field

[0001] The invention belongs to the technical field of mining machinery transportation, and in particular relates to a quick-type auxiliary transportation device and method for inclined tunnels without removing hooks. Background Art

[0002] Article 416 of the Coal Mine Safety Regulations stipulates that when transporting in inclined shafts and tunnels, the connection between the mine cars and the connection between the mine cars and the wire rope must use a connection device that cannot fall off on its own, and a safety rope must be installed. Each lifting requires removing the hook and connecting the safety rope, which is time-consuming and affects the lifting time.

[0003] Article 416 of the Coal Mine Safety Regulations stipulates that the connecting rings and connecting chains used in inclined lane hoisting must meet the tensile test of 2 times their maximum static load. If cracks are found or the permanent elongation exceeds 0.2%, they shall not be used. The rated traction of the traction head of the MGC-1.1 mine car used in our mine is 60KN, but in actual use, the traction of most hoists (winches) and wire ropes is much greater than 60KN when the safety factor specified in the Coal Mine Safety Regulations is met. This results in the relatively small traction of the connecting pins and chains, which limits the number of cars hoisted at one time and causes low hoisting efficiency.

[0004] During the process of removing the hook and fixing the safety rope, sometimes the operator's negligence may lead to missing hooks, improper hooking, or loose fixing of the safety rope, causing inclined tunnel transportation accidents. Summary of the invention

[0005] In view of the above problems, a new vehicle quick connection device is needed to solve the problem of long hook removal operation time, reduce the labor intensity of hook operators, increase the number of vehicles in a series during one lifting to improve operation efficiency and vehicle connection safety.

[0006] The technical solution of the present invention is as follows:

[0007] A quick-type auxiliary transportation device for inclined lanes without hook removal, comprising a plurality of rectangular covers with openings at the bottom connected in series; steel sections are fixed on the edges around the openings of the covers, steel plates are welded to the steel sections at the front and rear ends of the covers, pin holes are provided in the middle of the steel plates, and a handle is welded at the center of the top of the covers; a plurality of covers are connected in series into groups through connecting pins and connecting chains, wherein the front end of the first cover is connected to a lifting wire rope through a connecting pin.

[0008] Furthermore, the deformation of the steel sections around the edges of the cover opening does not exceed 0.2% under the tensile force of the maximum lifting weight.

[0009] Furthermore, the steel sections around the edges of the cover opening are fixed by welding or riveting.

[0010] Furthermore, when the steel section is fixed by welding, reinforcing ribs are used to assist in fixation.

[0011] A quick-type auxiliary transportation method for inclined tunnels without removing hooks uses a quick-type auxiliary transportation device, calculates the number of mine cars in a series vehicle group according to the use conditions such as the length of the upper and lower entrance yards of the inclined tunnel, connecting pins, connecting chains and the maximum static tension of the lifting wire rope, equips the lifting vehicle group with the number of cover bodies that need to be combined, and fixes them into groups using connecting pins and connecting chains, wherein the front end of the first cover body is connected and fixed to the lifting wire rope using the connecting pins; uses a mechanical arm to cover the fixed cover bodies on the mine car to complete the combination of the mine car and the cover body; and a traction device lifts the combination of the mine car and the cover body through the lifting wire rope.

[0012] The present invention provides an auxiliary device used in the connection of inclined lane lifting groups, which can quickly connect transport vehicles and avoid the operation of unhooking, thereby solving the problems of long unhooking operation time and high labor intensity of personnel, and improving operation efficiency and vehicle connection safety.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Improvements and modifications based on the present invention are within the scope of protection of the present invention.

[0017] The main feature of the present invention is that the operation of removing the hook is eliminated when the tandem vehicles are lifted, and the present invention mainly includes the tandem cover bodies 1 and the connections therebetween.

[0018] like Figure 1 and Figure 2 As shown, the cover body 1 is a rectangle with an opening at the bottom, and its outer dimensions are larger than those of the MGC-1.1, MGC-1.4 and other mine car compartments currently in use, so that it is convenient to cover the mine car without causing too large a gap;

[0019] The lower opening edge of the cover body 1 is welded and riveted with I-beams or other steel sections 2. Reinforcement ribs can be used to assist in fixing during welding. The overall structural strength is such that the deformation under the tensile force in both the vertical and horizontal directions at the maximum lifting weight does not exceed 0.2%;

[0020] Steel plates 3 are welded on the steel sections 2 at the front and rear ends of the cover body 1, and a pin hole 4 is provided in the middle of the steel plate 3. The diameter of the pin hole 4 meets the use requirements of the connecting pin 6, and the hole does not deform or crack under static tension when lifting the largest object;

[0021] A 0.5-meter-long No. 12 mining I-beam is welded on the top of the cover body 1 as a handle 5, which is convenient for the mechanical arm to grab and move the cover body 1. The material and structure used by the mechanical arm grabbing point can be other structures and methods that meet the use.

[0022] like Figure 3 As shown, according to the use conditions such as the length of the upper and lower entrance yards of the inclined tunnel, the maximum static tension of the connecting pin 6, the connecting chain 7 and the lifting wire rope 8, the number of mine cars 9 in the series train group is calculated, and the number of cover bodies 1 required to be combined in the lifting train group is equipped. The connecting pin 6 is inserted into the pin holes 4 at both ends of the cover body 1, and the connecting pin at the rear end of the front cover body is connected with the connecting pin at the front end of the rear cover body by using the connecting chain 7, so that all the cover bodies 1 are fixed into a group, wherein the front end of the first cover body 1 is connected to the lifting wire rope 8 through the connecting pin 6.

[0023] During operation, a group of auxiliary transport devices of the present invention is covered on the mine car 9 as a whole through a mechanical arm to complete the combination of the mine car 9 and the cover body 1, and the winch or other traction device is started to pull the lifting wire rope 8 to perform the lifting operation.
