Description

Track translation formula construction elevating platform

Technical Field

The invention belongs to the technical field of auxiliary equipment for engineering construction, and particularly relates to a rail translation type construction lifting workbench.

Background

The scissor fork type lifting device comprises a fixed scissor fork type lifting machine, a movable scissor fork type lifting machine, a self-propelled scissor fork type lifting machine, a vehicle-mounted scissor fork type lifting machine, a manual traction scissor fork type lifting machine and a special scissor fork type lifting ladder for carrying goods. The existing common scissor-type lifting device is special equipment for high-altitude operation, and the scissor-type lifting device has a scissor-type mechanical structure, so that a lifting platform is lifted to have higher stability, higher bearing capacity and a wide operation platform, the high-altitude operation range is larger, and the scissor-type lifting device is suitable for simultaneous operation of multiple persons.

The existing common scissor type lifting device is characterized in that a power source such as a hydraulic cylinder is arranged between included angles on two sides, lifting is achieved by expanding the included angles, or the power source is arranged between opposite sides of a parallelogram, and the lifting purpose is achieved by changing the distance between the opposite sides. One side of a shear type lifting frame of the existing shear type lifting device is hinged in a fixed shaft hole through a fixed pin shaft, and due to the fact that two sides shrink inwards after being folded, the other side of the shear type lifting frame must adopt a sliding pin shaft and must be sleeved in a transverse sliding groove to slide. On the other hand, because the included angle of the scissors fork of the scissors type lifting device is not suitable to be too large, the whole scissors fork support is inevitably required to be widened to replace the stability for improving the lifting height range, so that the material utilization rate is low, and the material cost is increased.

The scissor-fork type lifting device has the disadvantages that when the included angle is too large, although the whole height becomes high, the whole scissor-fork bracket becomes narrow and becomes high and is eccentric, so that the stability of the scissor-fork type lifting device becomes poor, and the included angle of the scissor-fork type lifting device cannot be too large for the stability of a working platform. In fact, only one pair of fixed pins is arranged at the bottom of the scissor type lifting device, and the other pair of fixed pins is sliding pins, so that the problems of the bracket narrowing and becoming high and the center shifting are necessarily caused as long as the bracket is unfolded. Therefore, after the working platform on the scissor type lifting device is lifted and is in a working state, the whole device is not easy to directly move, and although the base of the scissor type lifting device is provided with the walking wheels and even is driven by power, the walking wheels and the power-driven moving work are only limited to be in a contraction non-working state. When a working platform of the scissor type lifting device is unfolded to be in high-position working, the height of the working platform is generally required to be reduced when the working platform needs to be gradually translated along with the working progress, and the working platform is moved by a travelling wheel on a base of the working platform and then lifted to realize safe operation. In some construction environments with low ground flatness, the movement of the travelling wheels may bring about shaking of the whole device, and even cause toppling accidents due to unstable center. In a word, when the existing scissor-type lifting device is used, the stability of the bottom and the top is poor, the device is easy to shake due to external force, and the stability is poor along with the increase of the lifting degree.

To improve the stability of the existing scissor lift platform, a pothole protection mechanism of a self-walking scissor-type mobile lift platform is disclosed in CN 107827022 a, for example. The mechanism is arranged in the chassis and is connected with the scissor fork, the mechanism comprises connecting rod assemblies which are arranged in bilateral symmetry, one end of each connecting rod assembly is hinged with the chassis, a long pressing plate, a first fixing shaft, a short pressing plate and a second fixing shaft are sequentially arranged above the other end of each connecting rod assembly, and the second fixing shaft is connected with the scissor fork. The supporting plate can not be recovered when being subjected to large lateral force, and has stability, but as can be seen from the scheme and the attached drawings, the eccentricity degree of the supporting part is larger along with the increase of the height of the supporting plate, so that the integral stability of the supporting plate is poorer and poorer.

The utility model discloses a CN211813303U provides a cut fork elevating gear and cut fork aerial working platform, concretely relates to lift platform field, the on-line screen storage device comprises a base, four support plates of outside fixedly connected with of base, the bottom of support plate is equipped with the cylinder, the bottom of cylinder is equipped with the steel column, the top of base is equipped with telescopic bracket, telescopic bracket's top is equipped with a supporting bench, the equal fixedly connected with side platform in four sides of supporting bench, the one end of side platform is equipped with the reel, be equipped with the cable wire between reel and the support plate, this scheme is expected to improve its stability through cable wire all around, however in fact this platform is by the rising back, the supporting component still is in eccentric position, can only aggravate the pressure that eccentric supporting component bore through cable wire traction all around, influence the life of whole device.
