Description

Safety belt suspension system for subway deep foundation pit

Technical Field

The utility model relates to a subway construction technical field especially relates to a subway is safety belt suspension for deep basal pit.

Background

According to statistics, the high-altitude falling is the highest injury in the five major injuries in the building industry, so that how to prevent the high-altitude falling is very important. Although it is clearly specified in safety construction specifications that a hook or a rope of a safety belt should be hung on a firm member and a high-hanging and low-using mode is adopted, it is difficult for an operator to use the safety belt during high-altitude operation due to complicated field operation or limited field conditions. The deep foundation pit of subway also relates to high altitude construction, because the foundation pit span of subway is big and deep, constructor can often carry out the work of steel shotcrete erects and demolishs or formwork support erects, but constructor safety belt does not have the department to hang and establishes, very easily causes the eminence to fall. In addition, the erection of the safety equipment is time-consuming and labor-consuming, the whole operation area cannot be covered frequently, and the safety equipment needs to be erected repeatedly, so that the construction progress is greatly delayed.

General operating personnel hang the safety belt on the steel shotcrete prevents weighing down the rope when entering steel support frame is established or is demolishd, very easily causes the safety risk like this, perhaps operating personnel hangs the safety belt on the scaffold when setting up the scaffold, can become low string height usefulness like this, makes the guard action of safety belt weaken. Or some foundation pit side walls are utilized to set up the channel, the sliding fastener and the steel wire rope, so that the problems are solved, the setting up procedure is complicated, the construction and the dismantling need to be repeatedly carried out along with the construction of the subway structure, the operation cost is high, and the time is long.

Through searching the published patents, the following patent documents most relevant to the technical scheme are found:

the utility model provides a subway station foundation ditch steel shotcrete protection device that falls (CN208701696U) discloses a subway station foundation ditch steel shotcrete protection device that falls, includes the subway station foundation ditch body, and main arc backup pad assists the arc backup pad, prevents falling the buffer plate structure that collapses, and the fastening bolt nut, main tributary support steelframe, assistance support steelframe and adjustable safe stay check lock lever structure. The utility model discloses conventional bearing links up the seat, and the setting of main lock pole, lock nut, long nut, auxiliary lock pole and rotary rod is favorable to improving the support ability, through main lock pole and auxiliary lock pole under the cooperation of long nut, can carry out the support fastening work between main tributary support steelframe and the auxiliary support steelframe, avoids taking place main tributary support steelframe and auxiliary support steelframe and buckles and fall and take place danger; the anti-falling safety net, the drag hook, the lug plate and the connecting seat are arranged, so that the safety protection effect is improved, the main supporting steel frame and the auxiliary supporting steel frame are prevented from falling off and are directly hammered to constructors, and the constructors are guaranteed to withdraw from the site in time when danger occurs.

Through comparative analysis of the above published patent documents, the applicant believes that the seat belt suspension system in the present application has significant advantages in terms of easy disassembly and assembly, and convenient seat belt suspension at different heights, and the like, and the above patent does not affect the novelty of the present application through analysis.

The utility model provides a subway is safety belt suspension for deep basal pit, the top opening part of this subway deep basal pit has pour and has hat the roof beam, and fixed stay has a plurality of fender posts, its characterized in that between the bottom of hat the roof beam and the bottom of the pit of deep basal pit: a plurality of groups of longitudinal slide rails are oppositely arranged on the fender post in the deep foundation pit; the top of the crown beam is symmetrically provided with winches fixedly arranged by bolts, traction chains are wound on the winches, and the free ends of the traction chains penetrate through the crown beam downwards and lift and slide in the longitudinal slide rail; a plurality of safety beams are slidably mounted in the longitudinal slide rail, and two ends of each safety beam are detachably connected with the two oppositely arranged traction chains respectively.

And, the both ends of safety beam all make the location and lead to the groove, and this location is led to the inslot and is passed through positioning bolt fixed clamp and adorn the drag chain.

And one side of the longitudinal slide rail is fixedly connected with the side wall of the fender post, and the other side of the longitudinal slide rail is fixedly connected with the inner wall of the deep foundation pit through an expansion bolt.

The utility model has the advantages and the technical effect be:

the utility model discloses a safety belt suspension system for a subway deep foundation pit, which provides lifting power of a traction chain and a safety beam through a winch; horizontal displacement of the traction chain and the safety beam is restrained through the longitudinal slide rail, so that the safety beam is prevented from shaking to influence the body balance of construction personnel in the construction process; the structural strength of the longitudinal slide rail is strengthened through the guard piles and the pit wall of the deep foundation pit, so that the longitudinal slide rail is prevented from deforming under stress; through set up the location logical groove at safety beam both ends, realize being connected with dismantling of safety beam and drag chain, be convenient for increase and decrease the safety beam quantity on the drag chain because of the construction needs to convenient to dismantle and transport.

The utility model discloses a subway is safety belt suspension for deep basal pit, adopt the suspension of "rope ladder" formula, the dismouting and the transportation of the safety beam of being convenient for, and by the vertical displacement of hoist engine and haulage rope restriction safety beam, by the horizontal direction displacement of the inner wall restriction safety beam of vertical slide rail, the constructor of being convenient for hangs the safety belt on the safety beam, the event is safe construction scope along the extending direction of safety beam, when constructor need be when horizontal position perpendicular to safety beam extending direction motion, the accessible extension safety belt perhaps with the whole translation of dismantling of the safety belt suspension of this scheme to the construction position reinstallation can.
