Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the utility model and not to limit the scope of the utility model.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1 to 6, a heavy jack translation device for narrow space operation comprises a cantilever frame 1, a support base 2, a support seat 4, a top support frame 9 and a drive screw 10;
As a modification of the embodiment, the first mounting ear plate 201 and the second mounting ear plate 202 are mounted on the supporting base 2. The mounting lug plate I201 is welded on the front side of the support base 2, and one end of the cantilever frame 1 is hinged on the mounting lug plate I201; the second mounting lug plate 202 is welded in the middle of the support base 2, and the second mounting lug plate 202 is fixedly connected with the support base 4.
As an improvement of the embodiment, the connecting rod comprises a first connecting rod 5 hinged on the supporting seat 4 and a second connecting rod 8 hinged on the top supporting frame 9, the first connecting rod 5 and the second connecting rod 8 are hinged with each other through a reverse threaded rod 6 and a positive threaded rod 7, the driving screw 10 is respectively connected with the reverse threaded rod 6 and the positive threaded rod 7, when the driving screw 10 is rotated by a reciprocating pull handle, the reverse threaded rod 6 and the positive threaded rod 7 correspondingly rotate in a reverse direction and a forward direction under the action of the driving screw 10, the first connecting rod 5 and the second connecting rod 8 are driven to rotate along the joint of the reverse threaded rod 6 and the positive threaded rod 7, and then the top supporting frame 9 is controlled to lift, so that the jack mounting groove 101 on the top supporting frame 9 correspondingly lifts, and the mounting height of the heavy jack is met.
As the improvement of embodiment, connecting rod 5, connecting rod two 8 are equipped with four respectively, and every two connecting rod 5 and two connecting rod two 8 cooperation use, effectively satisfy the lift demand of top sprag frame 9, and overall structure steadiness is high.
As the improvement of embodiment, two walking wheels 3 that are located support base 2 front end are the universal wheel, and it is more convenient to remove.
The heavy jack translation device is 1.9 meters long and 0.68 meters wide, the upper part is a cantilever frame 1 and a top support frame 9 for lifting and suspending the heavy jack, the lower part is a support base 2 with 4 walking wheels (two of which are universal wheels), the upper part and the lower part are firmly connected through high-strength bolts, and the rated load capacity is 2 t.
The concrete construction steps are as follows:
the first step is as follows: firstly, turning a handle to rotate a driving screw rod 10 anticlockwise, driving a reverse screw rod 6 and a positive screw rod 7 to move towards two sides by driving the driving screw rod 10 to rotate, further enabling a connecting rod II 8 and a connecting rod I5 to rotate downwards around a hinged part, and enabling a jack mounting groove 101 of the cantilever frame 1 to descend to a position below lifting lugs on two sides of a jack; the translation device is pushed and adjusted manually, so that lifting lugs on two sides of a 500t jack are correctly corresponding to the jack mounting grooves 101 of the cantilever frame 1 of the translation device;
