The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.
As shown in Figure 1, a kind of chest formula lifting device that the utility model provides comprises:
Grab rope cam 2, described rope cam 2 one ends of grabbing are hinged in described first notch 4, the other end is a movable end, described movable end can be gone into and compresses the described climbing rope 20 that is arranged in described second notch 5 from described second notch, 5 one sidespins, and the lifting device body 3 between described first notch 4 and described second notch 5 is provided with one and is used to stop the described positioning convex 6 that rope cam 2 skids off from the opposite side of described second notch 5 of grabbing;
Be used to control the described rope cam 2 of grabbing and be rotated into control handle 1 in described second notch 5, the outer wall of described control handle 1 one ends and described first notch 4 is hinged, and the other end and described movable end of grabbing the cam 2 of restricting are hinged.
During use, as shown in Figure 1, when climbing rope 20 was arranged in second notch 5, the movable end of grabbing rope cam 2 was rotated into described second notch 5 and compresses climbing rope 20, and climbing rope 20 can only be slided along a direction.Climbing person is in climbing process upwards, and lifting device is subjected to the pulling force that downward load also is subjected to the climbing rope 20 that makes progress relatively simultaneously, and this pulling force acts on described grabbing on the rope cam 2.The positioning convex 6 that is provided with on the lifting device body 3 of the present utility model, can be used to stop that the described rope cam 2 of grabbing skids off from the opposite side of described second notch 5, when the angle of propelling movement lifting device is excessive in the prevention uphill process, climbing rope 20 can be jumped out lifting device, the lifting device that causes the user has improved the safety in utilization of lifting device from the danger that rope comes off.In addition, respectively there is one to tie hole 7,8 in the above and below of chest formula lifting device of the present utility model, the hole 7 of tiing of top is by chest formula lifting device fixed band (not shown) chest formula lifting device to be fixed on the front, the tiing hole 8 and can be connected with safety belt with safety button (not shown) of below.Chest formula lifting device of the present utility model is applicable to hand formula lifting device and uses jointly on rope, can effectively save muscle power when rising, and improves the rate of climb and efficient.
In the utility model, control handle 1 be used for control grab the rope cam 2 to described second notch, 5 inward turnings be diverted to compress the climbing rope 20.During climbing, pin control handle 1 downwards and drive and grab rope cam 2 and compress the climbing rope.Have friction owing to grab between end face and the climbing rope of movable end of rope cam 2, thus the user can rely on lifting device climb and on; The described control handle 1 that only need come up during decline can be accomplished slow decline, and is easy to use, safe.In the present embodiment, as preferably, described control handle 1 also is provided with is used to make the described back-moving spring (not shown) that rope cam 2 can screw out from described second notch 5 of grabbing when unclamping control handle 1 with the described rope cam 2 hinged ends of grabbing, described back-moving spring one end is connected with described control handle 1, and the other end is connected with described described movable end of grabbing rope cam 2.Such structure when rising owing to bear a heavy burden, climbing rope 20 with grab rope cam 2 and will be in impaction state always, back-moving spring then is in extended state.When climbing person uses chest formula lifting device alternately to change upwards, under the effect of back-moving spring elastic force, grab that rope cam 2 can slowly be pulled away from climbing rope 20 thereupon on chest formula lifting device of the present utility model so that climbing rope 20 can continue to slide until grabbing rope cam 2 locking climbing rope once more under the gravity effect.
Fig. 2 is the front view of grabbing the rope cam of the chest formula lifting device of an embodiment of the utility model.Fig. 4 is the front view of control handle of the chest formula lifting device of an embodiment of the utility model.As Fig. 2, shown in Figure 4, grab on rope cam 2 and the control handle 1 and be respectively arranged with fixing hole 23,24 and 13,14, be respectively applied for the described rope cam 2 of grabbing is connected with control handle 1 or with lifting device body 3.The projection 15 that is provided with on the described control handle 1 shown in Fig. 4 is used to connect back-moving spring.
As previously mentioned, as shown in Figures 2 and 3, the reason of using chest formula lifting device of the present utility model can conveniently climb rope is that lifting device itself can replace people's both hands tightly to buckle holding rope, and this critical component wherein is to grab rope cam 2 can clamp climbing rope 20 by frictional force.In the present embodiment, further, in order to promote described frictional force of grabbing between rope cam 2 and the climbing rope 20, play the effect of better firmly grasping stationary rope, as preferably, describedly grab the end face 22 that rope cam 2 can be rotated into an end of described second notch 5 and be provided with a plurality of ratchets 21 that are used to firmly grasp described climbing rope 20.Even this design make chest formula lifting device of the present utility model moist, freeze or muddy rope on use, it is also very outstanding to grab the rope ability.Further, as shown in Figure 3, describedly grab the end face 22 that rope cam 2 can be rotated into an end of described second notch 5 and be provided with dirt discharge groove 25.Like this freeze or muddy rope on when using chest formula lifting device also can by dirt discharge groove 25 easily the place to go dirt be beneficial to use.
The major advantage of chest formula lifting device of the present utility model is:
What one, the above and below of chest formula lifting device was provided with ties hole 7,8 when being buckled by attachment mean, can make chest formula lifting device be fixed on the operating position an of the best, can singlehanded buckle into any a section of rope.
Two, grab rope cam 2 in the chest formula lifting device of the present utility model and be generally steel chromium plating material, and design has dirt discharge groove 25 and ratchet 21, dirt discharge groove can conveniently clean, ratchet 21 makes rope slide towards a direction after buckling into climbing rope 20, improved the rope ability of grabbing, also made things convenient under atrocious weather and use.
Three, chest formula lifting device design of the present utility model meets ergonomics, and the control handle 1 that back-moving spring is housed makes when grabbing rope cam 2 normalities and is placed on the release position, and convenient one hand is installed or the chest formula lifting device of overcoming difficulties on climbing rope 20.
Four, the above and below of chest formula lifting device is provided with ties hole 7,8 and can be set to hole, special shape makes chest formula lifting device be close to belly, and the one side near chest is level and smooth, and the Shi Buhui that moves up along singly restricting causes the sensation of user's discomfort; And the tiing hole 8 and can be connected with other fall arrest equipment of below.
Chest formula lifting device of the present utility model applicable to: rescue, fire-fighting, military affairs, mountain-climbing, climbing, exploratory heading etc. need rope to rise and rope is gone up occasions such as location; as rising by dangerous area, precipitous landform, exploratory heading rises or during protection and the important self-protection equipment that is used of safety belt, main rope.
Certainly; the above is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
