Abstract

A guide track steering connector is utilized for holding apparatus with built-in or built-out guide tracks, which is suitable for operations high above ground level in fields of electric power, telecom, chemical industry and building. The utility model comprises a connection board and four radial guide tracks on the connection board, wherein two corresponding guide tracks are respectively arranged on a linear line. A rotating disc is positioned at the center of four guide tracks and pivoted with the connection board through a central pin shaft. In addition, a section of connecting guide track is fixed on the rotating disc and matches other paved guide tracks with the same end plane. Besides, the rotating disc can rotate along the central pin shaft to change guide track connection direction. While changing direction and guide track at crotch of guide tracks, the holding apparatus assembly is no need to be assembled and disassembled and just combined with the guide track to achieve the track replacement. The utility model has the advantages of high rigidness, simple structure, easy operation, great safety and reliability.

Description

Guide rail turns to connector

Technical field

The utility model relates to fall arrest lifesaving technical field of safety devices, especially relates to the guide rail that is used for the internal or external formula catching device of guide rail and turns to connector.

Background of invention

In industries such as the power transmission and transformation of power system, telecommunication, chemical industry work high above the ground is arranged all, need ascend a height; In building field, the construction of skyscraper, maintenance, maintenance also often relate to ascend operation, owing to there is not reliable falling-proof safety device, safety code can't be implemented, and causes the accident in the ascend operation to take place frequently; As China's power industry regulation, ascend operation must not lose the safety belt protection, and in fact, shaft tower can't be brought into play the safety belt effect up and down; The applicant has invented " the built-in catching device of guide rail " and " guide rail external catching device " two utility model patents for this reason, the patent No. is respectively ZL200420037471.1 and ZL200420037472.6, solved the fall arrest problem of ascending a height preferably, and applied; Guide rail is essential parts in these two patents, it is along being taped against the top on the structures, but structures can not be linked to be a straight line up and down, as the cable pylon that sets up in the power system, high-end cross-arm arranged at it, bifurcated stent is arranged, guide rail also needs bifurcated to lay at this place, and the fall arrest assembly in built-in catching device of guide rail and the guide rail external catching device is along a track combination, for commutating at the guide rail crotch and another guide rail goes combination, difficulty is quite big, and carries out the dismounting operation in the high-altitude, dangerous big, dangerous.

Summary of the invention

The purpose of this utility model is in order to address the above problem, provide a kind of guide rail to turn to connector, special and the supporting use of the internal or external formula catching device of guide rail, when guide rail crotch conversion guide rail, the combination of fall arrest assembly and guide rail does not need dismounting to switch tracks, and good rigidly, simple in structure, esy to use, safe and reliable.

For achieving the above object, the technical solution of the utility model is such: a kind of guide rail turns to connector, is installed on the guide rail infall, and with the supporting use of the internal or external formula catching device of guide rail, guide rail is that I-steel is made; One terminal pad is arranged, and radiant type is fixed 4 sections guide rails on the dish, wherein relative two sections guide rails each in a straight line, the guide rail that two straight line angulations press the actual laying of structures moves towards and decides, and is many with right-angled intersection usually; In the middle of four sections guide rails a rotating disk is arranged, this rotating disk is hinged by central pin shaft and terminal pad, fixes one section connection guide rail on the rotating disk, this connection guide rail and other guide rails of laying cooperatively interact, end face maintains an equal level, and rotating disk can rotate along the central pin shaft of terminal pad, changes guide rail closure.

Owing to adopted technique scheme, a kind of guide rail of the present utility model turns to connector, with the supporting use of the internal or external formula catching device of guide rail, when the guide rail crotch need change direction conversion guide rail, do not need the combination of dismounting fall arrest assembly and guide rail to switch tracks, and good rigidly, simple in structure, esy to use, safe and reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is Fig. 1 upward view.

Fig. 3 is a schematic perspective view of the present utility model.

Among the figure: 1, terminal pad, 2, guide rail, 3, rotating disk, 4, connect guide rail, 5, bearing pin, 6, spacer pin, 7, slotted eye.

The specific embodiment

By Fig. 1--shown in Figure 3, a kind of guide rail of the present utility model turns to connector, is installed on the guide rail infall, and with the supporting use of the internal or external formula catching device of guide rail, guide rail is that I-steel is made; One terminal pad 1 is arranged, and radiant type is fixed four sections guide rails 2 on the dish, wherein relative two sections guide rails 2 each in a straight line, the guide rail that two straight line angulations press the actual laying of structures moves towards and decides, and is many with right-angled intersection usually; One rotating disk 3 is arranged in the middle of four sections guide rails, and this rotating disk 3 is hinged by central pin shaft 5 and terminal pad 1, fixes one section connection guide rail 4 on the rotating disk 3, this connection guide rail 4 cooperatively interacts with guide rail 2, end face maintains an equal level, and rotating disk can rotate along the central pin shaft of terminal pad, changes guide rail closure;

In order to make rotating disk 3 rotate the accurate location that the back connects guide rail 4, on terminal pad 1, have two slotted eyes 7 with the axisymmetric circular arc of centrepin, and on the rotating disk 3 with each fixes a spacer pin 6 on the slotted eye 7 corresponding positions, this spacer pin 6 cooperates with slotted eye 7, can do relative slippage.

Claims (2)

1, a kind of guide rail turns to connector, be installed on the guide rail infall, with the supporting use of the internal or external formula catching device of guide rail, guide rail is that I-steel is made, it is characterized in that: a terminal pad (1) is arranged, radiant type is fixed four sections guide rails (2) on the dish, wherein relative two sections guide rails (2) respectively in a straight line, one rotating disk (3) is arranged in the middle of four sections guide rails, this rotating disk (3) is hinged by central pin shaft (5) and terminal pad (1), fix one section connection guide rail (4) on the rotating disk (3), this connection guide rail (4) cooperatively interacts with guide rail (2), and end face maintains an equal level.
