Abstract
The utility model relates to the technical field of drilling and well workover equipment, in particular to a special ladder stand used for a vehicle-mounted well workover machine. The technical scheme includes that the ladder stand comprises a ladder body and a connecting frame, wherein the ladder body is connected with the connecting frame through a plurality of quadrilateral mechanisms. Each quadrilateral mechanism comprises a rotating shaft and connecting rods, wherein the rotating shaft is connected with the connecting frame, and the connecting rods are connected with the two ends of the rotating shaft in hinged mode and are mutually parallel. The other ends of the two connecting rods are respectively connected with the ladder body in hinged mode. A torsional spring is arranged on the position where the rotating shaft and the connecting rods are hinged. Compared with the prior art, the special ladder stand used for the vehicle-mounted well workover machine has the advantages that the quadrilateral mechanisms are ingeniously applied to the ladder stand, and therefore the ladder stand is multipurpose, materials are saved, and cost is lowered; the quadrilateral mechanisms are matched with the torsional spring in using, and therefore potential safety hazards of the weight of the traditional ladder is eliminated, and labor intensity of operational staff is relieved; the ladder stand is fast and convenient to operate, simple in structure, and strong in practicability and generalization performance; and the ladder stand is small in size and convenient to install and transport.
Description
Technical field
The present invention relates to the drilling and repairing well equipment technical field, is specifically related to a kind of vehicle carried well repairing machine special ladder.
Background technology
Cat ladder weight on the vehicle carried well repairing machine is heavier at present, volume is larger, and its labour intensity when folding and unfolding is very large, and also is not easy to transportation, also has simultaneously potential safety hazard when folding and unfolding and transportation.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, easy to operate, vehicle carried well repairing machine special ladder of being convenient to transport.
The present invention is achieved by the following technical solutions: comprise ladder body and link, wherein the ladder body is connected with link respectively by a plurality of quadrangular mechanisms, and described quadrangular mechanism comprises the rotating shaft that connects with link, distinguishes hinged and parallel connecting rod each other with the rotating shaft two ends; The other end of described two connecting rods is hinged with the ladder body respectively; Described rotating shaft and rod hinge connection place are provided with torsion spring.First link and vehicle-mounted operating platform are fixed during use, when transferring the ladder body, both sides connecting rod synchronous rotation axle rotates under Action of Gravity Field, progressively open quadrangular mechanism downwards, thereby being transferred, the ladder body puts, and because the torsion of torsion spring gravity that can partial offset ladder body in place, therefore the ladder body is slowly transferred, play the effect of safeguard protection; When needs are packed up this device, on carry the ladder body, both sides connecting rod synchronous rotation axle backward rotation, progressively upwards pack up quadrangular mechanism, foldable integral is packed up, pack up in the process since torsion spring from nerve, can be driven by quadrangular mechanism just with very little power that the ladder body is up to be packed up.
Also be hinged with handrail on the described ladder body, it can play a protective role in working order the time, during off working state (such as travel position), can fold and bounce back with the ladder body and pack up.
Described special ladder also comprises retaining mechanism; link, quadrangular mechanism, ladder body and handrail can be tightened and the location; one can prevent that it is subjected to displacement when transportation; and after locking is integrated, can play the guardrail protective effect to the work card tool on the vehicular platform in the transportation.
The bottom of described link also connects the baffle plate for positioning linkage rod, namely when transferring the ladder body, can make the ladder body in place by positioning linkage rod.
Than prior art, the present invention has the following advantages:
(1), be applied on the pedal ladder quadrangular mechanism is ingenious, a ladder is multiplex, saves material, reduces cost.
(2), being used in conjunction with of quadrangular mechanism and torsion spring, eliminated the potential safety hazard on traditional ladder weight, alleviated operating personnel's labour intensity.
(3), swift and convenient to operate, simple in structure, have very strong practicality and generalization.
(4), volume is little, be convenient to install, transportation.

The specific embodiment
The present invention will be further described referring to accompanying drawing.
With reference to Fig. 1,5 and 6, a kind of vehicle carried well repairing machine special ladder comprises link 3, ladder body 1 and hinged handrail 2, and wherein ladder body 1 is connected with link 3 respectively by a plurality of quadrangular mechanisms; Quadrangular mechanism comprises the rotating shaft 6 that connects with link 3, distinguishes hinged and parallel connecting rod 4 each other with rotating shaft 6 two ends; The other end of two connecting rods 4 is hinged with ladder body 1 respectively; Rotating shaft 6 is provided with torsion spring 8 with connecting rod 4 hinged places; The bottom of link 3 also connects for the baffle plate 8 of positioning linkage rod 4 and retaining mechanism 5 that integral locking is integrated.
Concrete using method is as follows:
(1), opens rear duty: first link 3 and vehicle-mounted operating platform are fixed; when transferring ladder body 1; connecting rod 4 synchronous rotation axles 6 in both sides rotate under Action of Gravity Field; progressively open quadrangular mechanism downwards, put in place thereby ladder body 1 is transferred, and because the torsion of torsion spring 8; gravity that can partial offset ladder body; therefore the ladder body is slowly transferred, play the effect of safeguard protection, concrete state is referring to Fig. 2.
(2), retraction is packed up and locking state: when needs are packed up this device, at first handrail 2 is folded with the ladder body and recline, then carry ladder body 1 on, both sides connecting rod 4 synchronous rotation axles 6 backward rotation, progressively upwards pack up quadrangular mechanism, foldable integral is packed up, and with retaining mechanism 5 quadrangular mechanism, ladder body and handrail are locked relatively.Pack up in the process since torsion spring 8 from nerve, can be driven by quadrangular mechanism just with very little power that the ladder body is up to be packed up.
Above-described embodiment only is a kind of typical embodiment of the present invention; but embodiments of the present invention are not restricted to the described embodiments; any change, modification that does not deviate from its essence and principle that those skilled in the art make on its basis, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
