Abstract

The utility model provides a suspended cable bearer used for the upper part of an underground tunnel, which belongs to the technical field of cable laying. The utility model is to provide a suspended cable bearer used for the upper part of an underground tunnel, which is installed firmly, suspended and taken down conveniently, is labor-saving and time-saving as well as saves material. The technical essence of the utility model is as follows: the suspended cable bearer comprises a bearer girder, lifting lugs and a U-shaped hook; side boards on both sides of the upper end of the opening of the U-shaped hook (2) are provided with hooks (21) turning outwards; the hooks (21) are matched with and joined with clamp grooves (31) correspondingly arranged on the lifting lugs fixed on the bearer girder. As the hooks turning outwards matched and joined with the hook grooves arranged on the lugs are arranged on the upper end of the U-shaped hook on both sides, cables can be supported in the U-shaped hook conveniently to be sealed, and cables can be disassembled and put conveniently to maintain and replace. Compared with the prior cable bearer, the suspended cable bearer has the advantages of safety, firmness, saving labor, saving time and saving trouble.

Description

The suspended cable carriage that is used for underworkings top

Technical field

The utility model relates to a kind of suspended cable carriage that is used for underworkings top, belongs to the cable laying technical field.

Background technology

At present, in the colliery, particularly mine is than dark and the bigger mine of gas amount, and production facilities such as the pipeline in its tunnel, cable, transportation and ventilation are numerous, and only one of pipeline just can reach more than eight.As: cooling, gas exhaust, notes nitrogen, grouting, pressure wind, draining, supply channel etc.And two the nozzle diameter of cooling pipeline and a gas exhaust pipeline is all more than 300mm, and the nozzle diameter of air line is added the space hold of facility such as air duct also more than 200mm, makes the layout of drift section use very crowded.Disturb for avoiding facility, cable is laid to the top, tunnel.And existing cable tray adopts the cable hook of traditional common open type usually, and usually there is the danger that comes off in cable in the use of top, tunnel.Use the U type to embrace the cable that the card bolt connecting mode is fixed, connect reliably though hang, the workload of installing is bigger, and maintenance management is also relatively more difficult.Not only every cable will use two bolts on each armful card when mounted, and in production run in the future, need to safeguard and when changing cable, to produce huge disassemble and assemble work amount equally, and take the very long power failure off-time, cause bigger influence to production, also increased maintenance cost simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of and installs firmly, hang the suspended cable carriage that is used for underworkings top of plucking convenience, saving of labor, saving time, save trouble.

Its technical scheme is: a kind of suspended cable carriage that is used for underworkings top, it is characterized in that: form by truss girder, hanger and the hook of U type, both sides, the oral area of U type hook upper end side plate is respectively arranged with the hook of outside turnover, and this hook can mate with the corresponding screens groove of offering on a plurality of hangers on being fixed on truss girder and articulates.

Its technique effect is: owing to both sides, the oral area of U type hook upper end side plate outwards is folded into the hook that can articulate with the screens groove coupling offered on the hanger respectively, so it can either prop up cable in U type carriage easily, realization is to the closed assembling of cable, loan at call cable is easily again realized easily maintenance and replacing to cable.Compare with existing cable tray, have safety, firmly, saving of labor, the advantage that saves time, save trouble; Simultaneously, adopt truss girder to cooperate the version of installing with top, tunnel, the specification and the quantity of cable can be installed according to the scene, choose and be applicable to U type hook that the different size cable uses and the hanger that articulates with U type hook coupling, with the many upper spaces that are suspended on the tunnel that cable is neat, orderly, not only avoided the interference of other facilities such as pipeline, satisfied the needs of safety in production, and improved roadway quality standardization level; In addition, all members of this cable tray can adopt die stamping to be processed into, and make its dimensional standard standard, has good interchangeability, the surface of member can also be carried out zinc-plated or plastic-blasting is handled, and makes its surface not only bright and clean attractive in appearance, but also has corrosion-resistant effect.Therefore, cable tray of the present utility model is a safety economy type standardized cable carriage comparatively desirable at present, that be fit to upper space use under the coal mine.

Embodiment

As shown in Figure 1, a kind of suspended cable carriage that is used for underworkings top is made up of truss girder, hanger and the hook of U type.U type hook 2 is a muscle slot type structure.After its both sides, oral area upper end side plate outwards turns down 90 degree respectively, turn down 90 degree downwards and form hook 21.Hanger 3 is the inverted "L" shaped shape, offers screw on its top, is fixed on the truss girder 1 by bolt.Truss girder is provided with a plurality of hangers 3, and hanger is provided with screens groove 31, and this screens groove can articulate (see figure 2) with the hook 21 corresponding couplings that both sides, U type carriage oral area upper end side plate outwards turns down.

Can successfully enter in the screens groove 31 on the hanger for the ease of the hook 21 on the U type carriage, the top of screens groove one side offers parallel fitting recess 32.

Truss girder is a trench structure, offers the regulating tank 11 and 12 of construction bolts that is 90 degree mutually on the hangers at its two ends, truss girder and top, tunnel can be connected and fixed by bolt, and can be in the installation site of an amount of adjustment truss girder on the both direction in length and breadth.

During use, the spacing of truss girder according to 800-1000mm laterally is installed on the base plate on top, tunnel inclination maximum a＜60 between truss girder and top, the tunnel base plate °.When cable is installed, earlier cable is placed in the U type carriage, then both sides, U type hook oral area upper end side plate is outwards turned down the hook of formation, the parallel fitting recess of offering on the hanger pushes, it is dropped in the screens groove, realize that the corresponding coupling with the screens groove of hook articulates, and form self-locking.When maintenance or replacing cable,, make the hook of its both sides leave the screens groove, outwards pull out along fitting recess again, can emit cable, repair or replace as long as the hook of U type is held up.
