Abstract
A kind of preventing wire rope from falling pulley groove device, comprises arm head side plate, fixed pulley bearing pin, fixed pulley group.The utility model is equipped with the fender rod that can move freely on fixed pulley group side, and install a gear rope sheave additional, gear rope sheave is while can rotate around fender rod, while can contact with fixed pulley group, so just reach adjustability, and be connected with arm head side plate spring respectively at fender rod two ends, gear rope sheave on fender rod can be rotated with fixed pulley group close fit, thus moving in fixed pulley groove of making that steel rope can be very stable, and pulley groove can not be departed from, if just in case steel rope out, external force can be used to make spring elongates, such gear rope sheave is just separated with fixed pulley group, just can when not tearing assembly pulley open, steel rope is loaded into.
Description
Technical field
The utility model relates to lorry-mounted crane technical field, is specifically related to a kind of preventing wire rope from falling pulley groove device.
Background technology
Existing preventing wire rope from falling slot device is comparatively simple, is generally by fixed pulley group, is parallel to assembly pulley axis direction and is welded with round steel fender rod; Or conveniently turn back in groove after being convenient to steel cable slot disengaging, fender rod is made detouchable.Their principle reduces fender rod and gap, pulley limit as far as possible, its gap is made to be less than wirerope diameter, such steel rope is due to the effect of fender rod, be not easy to spin off from pulley groove, but the mode of this anti-dislocation preventing slot just considers the indeformable situation of pulley, and has the situation of pulley stress deformation time in reality.When after pulley distortion, the gap of fender rod and pulley is strengthened, simultaneously steel rope also ovalisation cross section when stressed, such steel rope is easy to de-groove, and at present in order to reduce weight and cost, a lot of pulley material is from steel part, and foundry goods makes high-strength nylon into, the stressed rear distortion of such pulley is larger, and steel cable slot disengaging probability just increases greatly.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of preventing wire rope from falling pulley groove device, and the gap that auto-compensation causes due to pulley distortion becomes large, and effective anti-limited slip wheel takes off groove.
The technical solution of the utility model is: a kind of preventing wire rope from falling pulley groove device, comprise arm head side plate, fixed pulley bearing pin, fixed pulley group, arm head side plate is processed with pin shaft hole, fixed pulley bearing pin passes pin shaft hole and is fixed on arm head side plate, fixed pulley group is fixed on fixed pulley bearing pin, it is characterized in that, an oval groove is respectively had on arm head side plate both sides, there is a fender rod through oval groove and move freely in oval groove, fender rod two ends are connected with the spring fixed end being welded on arm head side plate both sides respectively by respective extension spring, fender rod is combined with a gear rope sheave rotated around fender rod, gear rope sheave is processed with rectangular recess, each pulley of fixed pulley group to be stuck in the rectangular recess on gear rope sheave and contact also engaged transmission with gear rope sheave groove floor.
Advantage of the present utility model: the utility model is equipped with the fender rod that can move freely on fixed pulley group side, and install a gear rope sheave additional, gear rope sheave is while can rotate around fender rod, while can contact with fixed pulley group, so just reach adjustability, and be connected with arm head side plate spring respectively at fender rod two ends, gear rope sheave on fender rod can be rotated with fixed pulley group close fit, thus moving in fixed pulley groove of making that steel rope can be very stable, and pulley groove can not be departed from, if just in case steel rope out, external force can be used to make spring elongates, such gear rope sheave is just separated with fixed pulley group, just can when not tearing assembly pulley open, steel rope is loaded into.
Accompanying drawing explanation
Fig. 1 is the utility model structure birds-eye view.
Detailed description of the invention
Now in conjunction with the following drawings, utility model is described in detail.
See Fig. 1, arm head side plate 1 is processed with pin shaft hole, fixed pulley bearing pin 2 passes pin shaft hole and is fixed on arm head side plate 1, fixed pulley group 3 is fixed on fixed pulley bearing pin 2, an oval groove 1.1 is respectively had on arm head side plate 1 both sides, there is a fender rod 4 through oval groove 1.1 and can move freely in oval groove 1.1, so just reach adjustability, fender rod 4 two ends are connected with the spring fixed end 1.2 being welded on arm head side plate 1 both sides respectively by respective extension spring 5, fender rod 4 is combined with a gear rope sheave 6 rotated around fender rod 4, gear rope sheave 6 is processed with three rectangular recess 6.1, each pulley of fixed pulley group 3 to be stuck in the rectangular recess 6.1 of gear rope sheave 6 and contact also engaged transmission with gear rope sheave groove 6.1 bottom surface.
Gear rope sheave 6, while rotate around fender rod 4, forms fixed pulley group 3 with 3 fixed pulleys side by side in fixed pulley group 3(figure) close contact engages, and gear rope sheave 6 rotated with fixed pulley group 3.Under the effect of extension spring 5, even if fixed pulley group stress deformation, gear rope sheave 6 and fixed pulley group 3 close contact all the time, such steel rope out, can not reach the effect preventing steel cable slot disengaging.If just in case steel rope is out, external force can be used to make spring elongates, keep off rope sheave like this and be just separated with fixed pulley group, just can when do not tear open pulley to, steel rope is loaded into.
