The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is done further detailed explanation.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 8, a kind of pin formula lifting device provided by the invention comprises:
Grab rope cam 2; Said rope cam 2 one ends of grabbing are hinged in said first notch 8; The other end is a movable end; Said movable end can be gone into and compresses said climbing rope from said second notch, 9 one sidespins, and the lifting device body 3 between said first notch 8 and said second notch 9 is provided with one and is used to stop the said positioning convex 1 that rope cam 2 skids off from the opposite side of said second notch 9 of grabbing;
Fixing ribbon; Said fixedly ribbon comprises and is used for foot-operated ribbon 5 that said lifting device body 3 is frapped and tramples at the adjustable ribbon 4 in the outside of user foot and person's easy to use pin, and the ribbon adjusting button 6 on the adjustable ribbon 4 can be used for going up according to the size so that said that different users regulates adjustable ribbon 4 and rises body 3 and can suitablely be fixed rightly; Said foot-operated ribbon 5 one ends are connected with said adjustable ribbon 4, and the other end is connected with said lifting device body 3.In addition, can also set up the intensity that the reinforcement (not shown) increases foot-operated ribbon 5 on the foot-operated ribbon 5 of the fixedly ribbon of pin formula lifting device of the present invention as required.
During use,, grab rope cam 2 and be rotated into said second notch 9 and compress the climbing rope, the climbing rope can only be slided along a direction when climbing rope when being arranged in second notch 9.Climbing person can make lifting device rise along rope through foot action in climbing process upwards, but because grab compressing of rope cam 2, rope can not upwards slide with respect to lifting device, so the user can locate on rope when trampling.The positioning convex 1 that is provided with on the lifting device body 3 of the present invention; Can be used to stop that the said rope cam 2 of grabbing skids off from the opposite side of said second notch 9; When the angle of propelling movement lifting device is excessive in the prevention uphill process; The climbing rope can be jumped out lifting device, and 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, as shown in Figures 2 and 3, pin formula lifting device body 3 of the present invention is provided with a plurality of holes 34,35 of tiing.Fig. 4 and Fig. 5 show the lifting device body of pin formula lifting device of the present invention and the syndeton sketch map of adjustable ribbon; As shown in the figure; Tiing hole 34 is to be used to make the lifting device body to be arranged in adjustable ribbon 4; Tiing hole 35 then is to be used to connect foot-operated ribbon 5, forms and is available for users to the structure that pin is trampled.
In the present invention, as shown in Figure 4, as preferably, said hinged end of grabbing rope cam 2 and said lifting device body 3 also is provided with and is used to make the said back-moving spring 7 that rope cam 2 screws in to said second notch 9 of grabbing.Because the elastic force effect of back-moving spring 7, the climbing rope with grab rope cam 2 and will be in impaction state always.When climbing person need install or change climbing during rope, only need move and grab rope cam 2 and get final product with hand, back-moving spring 7 is in compressive state at this moment.
As previously mentioned; Like Fig. 6 and shown in Figure 7; The reason of using pin formula lifting device of the present invention 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 the climbing rope through frictional force.In the present embodiment; Further; In order to promote said frictional force of grabbing between rope cam 2 and the climbing rope; Play the better promptly effect of stationary rope, as preferably, saidly grab the end face 22 that rope cam 2 can be rotated into an end of said second notch 9 and be provided with a plurality of ratchets 21 that are used to firmly grasp said climbing rope.Even this design make pin formula lifting device of the present invention moist, freeze or muddy rope on use, it is also very outstanding to grab the rope ability.Further, as shown in Figure 3, saidly grab the end face 22 that rope cam 2 can be rotated into an end of said second notch 9 and be provided with dirt discharge groove 25.Like this freeze or muddy rope on when using pin formula lifting device also can through dirt discharge groove 25 easily the place to go dirt be beneficial to use.
Fig. 9 is the making flow chart of pin formula lifting device of the present invention.As shown in the figure, the preparation method of a kind of pin formula lifting device provided by the invention comprises the steps:
1) chooses No. 6061 aluminium of raw material, and strike out the blank of lifting device body 3;
The blank of the said lifting device body 3 that 2) step 1) is obtained is heat-treated, and solid solubility temperature is 480～550 ℃, and solution time is 2～3 hours, and aging temp is 150～180 ℃, and aging time is 5～8 hours;
3) will pass through step 2) blank of said lifting device body 3 after the heat treatment is cut edge respectively, punching, surface finish and anodized, forms lifting device body 3;
4) the said lifting device body 3 that step 3) is obtained assembles with fixing ribbon with the said rope cam 2 of grabbing, and forms described pin formula lifting device.
The present invention carries out T6 heat treatment to said lifting device body 3; Improved the defective of the die casting internal loose that other heat treatment modes of available technology adopting exist, the stability that pore and aeration die casting internal structure are arranged etc., made the internal structure of lifting device body 3 of the present invention more stable.T6 heat treatment is a kind of Technology for Heating Processing of wrought aluminium alloy (being different from Birmasil); It is the process of " solution treatment (being called " quenching ")+artificial aging " for this process of iron and steel; Wherein principal element is solid solubility temperature, solution time, aging temp, constant temperature time.The T6 Technology for Heating Processing is to solve intensity, the plasticity reasonably combined (high intensity and enough plasticity) of material and the key of corrosion resistance.
As preferably, the constituent of the said lifting device body 3 that step 3) obtains is:
