Background technology
Along with the development of urbanization, avenue network of underground increases just year by year, ground has occurred a lot of well lids, has related to the underground communal facilitys such as electric power, communication, water supply, heating, coal gas, draining.As the maintainer of communal facility, to enter frequently by vertical shaft maintenance and the tour work that tunnel carries out equipment.Because in vertical shaft, cat ladder top is only set to well head place, do not have around the well head on ground to climb the fastening devices of holding up, Construction and Maintenance personnel pass in and out well, between shoulder bassets and to basset to pin, there is no the application point that can grip, add the difficulty that constructor goes into the well, more easily fall, reduce safety.Simultaneously, according to electric power safety code, staff is when depth of falling well is more than 2 meters, anti-drop device should be used to carry out security protection, because the degree of depth of vertical shaft differs, constructor in the process of going into the well in order to increase safety, need to dress arrest devices, but do not possess the fastening devices of arrest devices in existing vertical shaft, maintainer usually to catching device hang with carrying out high with or determine fixed point according to condition temporarily, take time and effort and easily cause potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of structure simple, easy to use, strengthens vertical shaft operational security, facilitate personnel to pass in and out the vertical shaft anti-drop device of vertical shaft.
The technical scheme that the utility model solves the employing of its technical problem is: a kind of vertical shaft anti-drop device, it support bar comprising cat ladder, be arranged on the fixed frame of cat ladder bottom, be fixedly installed on the fall prevention frame on cat ladder top and be arranged on inside fixed frame, described fixed frame is " convex " font of lower ending opening, the U-shaped frame that described fixed frame comprises top and the holding frame be connected with described U-shaped frame, two curb girders of described U-shaped frame and cat ladder are hinged by axle, and described holding frame lateral dimension is greater than well head diameter; Described support bar one end and U-shaped frame are hinged by axle, and the movable end of described support bar arranges through hole, and the curb girder of described cat ladder arranges the locating hole that arrange corresponding to through hole, and described through hole is connected by pin with locating hole; The two ends of described fall prevention frame are fixedly connected with two curb girders of cat ladder respectively.Described through hole and locating hole in the same size, the movable end of support bar rotates and can realize through hole and overlaps with locating hole, makes pin simultaneously through through hole and locating hole, realization connection.
The lateral dimension of described holding frame refers to " convex " font frame Far Left and rightmost vertical distance.
Preferably, described fall prevention frame comprises the cross bar be connected with catching device and the montant be connected with curb girder, and one end of described cross bar is connected with curb girder by two montants, and in side direction, montant and curb girder form triangle.
Optimum, described cross bar is fixedly installed the retainer ring be connected with catching device.
Cat ladder of the present utility model is prior art, the multiple crossbeams comprising two curb girders and be arranged between curb girder, and cat ladder width is less than vertical shaft diameter to be onstructed; The width of described U-shaped frame and cat ladder width adequate, during with U-shaped frame place plane and cat ladder place planes overlapping, cat ladder top lived by U-shaped frame energy frame is good.
Good effect of the present utility model is:
1, fall prevention frame provides fixed point for catching device, and the hook hook of catching device is fixed on cross bar or retainer ring, easy to operate, fixation, construction safety, catching device more can be avoided to horizontally slip when hanging over retainer ring, improves stability;
2, as the extension on vertical shaft cat ladder top, constructor upper to can grip during ground cat ladder of the present utility model and continue along on cat ladder more than ground, upper well is more convenient and safe;
3, by horizontal level and the angle of inclination of the vertical position of fixed frame determination cat ladder, support bar and pin location cat ladder, strengthen the stability that cat ladder is fixing, avoid rocking and swinging of cat ladder, improve construction safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
In accompanying drawing, 1 cat ladder, 11 curb girders, 2 fixed frames, 21U type frame, 22 holding frames, 3 support bars, 4 pins, 5 fall prevention frames, 51 cross bars, 52 montants, 53 retainer rings.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, below in conjunction with the drawings and specific embodiments in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
As shown in Figure 1, the support bar 3 that the present embodiment comprises cat ladder 1, is arranged on the fixed frame 2 of cat ladder 1 bottom, is fixedly installed on the fall prevention frame 5 on cat ladder 1 top and is arranged on inside fixed frame 2, described fixed frame 2 " convex " font in lower ending opening, the U-shaped frame 21 that described fixed frame 2 comprises top and the holding frame 22 be connected with described U-shaped frame, two curb girders 11 of described U-shaped frame and cat ladder 1 are hinged by axle, and described holding frame 22 lateral dimension is greater than well head diameter; Described support bar 3 one end and U-shaped frame 21 are hinged by axle, and the movable end of described support bar 3 arranges through hole 31, and the curb girder 11 of described cat ladder 1 arranges the locating hole 12 that arrange corresponding to through hole 31, and described through hole 31 is connected by pin 4 with locating hole 12; The two ends of described fall prevention frame are fixedly connected with two curb girders 11 of cat ladder 1 respectively.
