Background technology
In Current Engineering Construction field, use widely hydraulic jack thrustor. In the time that the distance of pushing tow is long, need hydraulic jack successively repeatedly the stroke of pushing tow superposeed omnidistance incremental launching construction task.
Conventionally in the time using hydraulic jack pushing tow technology to pass weight, must there is counter-force seat after oil cylinder. The stack construction of pushing tow stroke need to be repeatedly by the dismounting of counter-force seat, moves forward and install fixing, repeats loaded down with trivial detailsly, and consuming time many, work consuming is large. In addition, counter-force seat, in the process of installing/dismounting repeatedly, easily causes distortion and the wearing and tearing of pushing tow track, and this also there will be wearing and tearing counter-force seat in long-term use, needs timing to change, thereby has increased the cost of construction.
Summary of the invention
The object of the invention is to overcome the deficiency of existing thrustor, and proposed a kind of walking type pushing device based on rolling and sliding friction.
The walking type pushing device based on rolling and sliding friction that the present invention proposes, is made up of vertical hydraulic jack, horizontal hydraulic pipe bending cylinder, slippage guide rail, pushing tow roller set, Mobile base, pedestal and base; Two vertical hydraulic jacks are fixed on base, and are positioned at the both sides, front and back of pedestal, for supporting by pushing thing; Pedestal is fixed on base by bolt-connection; Pedestal is integrally welded by a transverse slat and two risers, and a pair of horizontal hydraulic pipe bending cylinder and a pair of slippage guide rail are installed in pedestal, and the two ends of horizontal hydraulic pipe bending cylinder and slippage guide rail are fixed between two montants of pedestal by flange connect respectively; Wherein horizontal hydraulic pipe bending cylinder is two-way cylinder, the piston rod at its two ends connects with pedestal, the cylinder block of horizontal hydraulic pipe bending cylinder and slippage guide rail are respectively through Mobile base, cylinder block and Mobile base are integrated by flange connect, and Mobile base can be made bidirectional reciprocating axial slip along slippage guide rail direction; Pushing tow roller set has some groups, and every group of pushing tow roller set connected to form by roller and roller column; Roller column is fixed on the upper surface of Mobile base by bolt-connection, described pushing tow roller set is in one line on Mobile base; Between pushing thing and pushing tow roller set, remained contact condition; Each pushing tow roller set is provided with enclasp device, can realize synchronously holding tightly or unclamping of roller; In the time that roller is releasing orientation, roller and by between pushing thing for rolling friction; When roller is when holding state tightly, roller and be sliding friction between pushing thing; In Mobile base slipping, pushing tow roller set is with the slippage of Mobile base Integral synchronous; By the collaborative work of vertical hydraulic jack and horizontal hydraulic pipe bending cylinder, and the holding tightly and unclamp of roller, thereby realize the automation pushing tow operation of thrustor.
In the present invention, described pushing tow roller set, depending on concrete situation, is generally 4-6 group.
The present invention has following several large advantages:
(1) this thrustor is simple in structure, dependable performance, and cost is low;
(2) this thrustor is in the course of the work without manual operation, and automaticity is high;
(3) in pushing tow process, the position of thrustor immobilizes, without dismounting repeatedly, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further elaborated.
Embodiment 1: as shown in the figure, the walking type pushing device based on rolling and sliding friction is made up of vertical hydraulic jack 1, horizontal hydraulic pipe bending cylinder 2, pushing tow roller set 3, base 7, pedestal 8, Mobile base 9 and slippage guide rail 10. Vertical hydraulic jack 1 is fixed on base 7, is positioned at the both sides, front and back of pedestal 8, for supporting by pushing thing 6. Pedestal 8 is fixed on base 7 by bolt-connection. A pair of horizontal hydraulic pipe bending cylinder 2 and a pair of slippage guide rail 10 are installed in pedestal 8, and the two ends of horizontal hydraulic pipe bending cylinder 2 and slippage guide rail 10 are fixed on pedestal 8 by flange connect respectively. Wherein horizontal hydraulic pipe bending cylinder 2 is two-way cylinder, the piston rod at two ends connects with pedestal 8, cylinder block and slippage guide rail 10 are through Mobile base 9, and cylinder block and Mobile base 9 are integrated by flange connect, can realize the bidirectional reciprocating axial slip of Mobile base 9 along slippage guide rail 10 directions. Pushing tow roller set 3 is four groups, and every group of roller set is made up of roller 4 and roller column 5. Roller column 5 is fixed on the upper surface of Mobile base 9 by bolt-connection, in one line on Mobile base 9. Between pushing thing 6 and pushing tow roller set 3, remained contact condition. Each roller set is provided with enclasp device, can realize synchronously holding tightly or unclamping of roller 4. In the time that roller 4 is releasing orientation, roller 4 and by between pushing thing 6 for rolling friction. When roller 4 is when holding state tightly, roller 4 and be sliding friction between pushing thing 6. In Mobile base 9 slippings, pushing tow roller set 3 is with Mobile base 9 Integral synchronous slippages. By the collaborative work of vertical hydraulic jack 1 and horizontal hydraulic pipe bending cylinder 2, and the holding tightly and unclamp of roller 4, thereby realize the automation pushing tow operation of thrustor.
The course of work of the present invention is specific as follows:
1) as shown in Fig. 3 (a), thrustor is in initial state. Vertical hydraulic jack 1 with contacted by pushing thing 6, play a supportive role;
2) as shown in Figure 3 (b), vertical hydraulic jack 1 shrinks, until with departed from by pushing thing 6. Supported by pushing tow roller set 3 by pushing thing 6, now the roller 4 in pushing tow roller set 3 is in holding state tightly, roller 4 and be sliding friction between pushing thing 6;
3) as shown in Figure 3 (c), horizontal hydraulic pipe bending cylinder 2 carries out pushing tow operation, drives pushing tow roller set 3, and being moved forward by pushing thing 6 of being supported by pushing tow roller set 3;
4) as shown in Fig. 3 (d), vertical hydraulic jack 1 extends, until with contacted by pushing thing 6. Supported by vertical hydraulic jack 1 by pushing thing 6;
5), as shown in Fig. 3 (e), horizontal hydraulic pipe bending cylinder 2 operation that resets, drives pushing tow roller set 3 to move backward, is kept motionless by pushing thing 6. Now the roller 4 in pushing tow roller set 3 is in releasing orientation, roller 4 and be rolling friction between pushing thing 6. Horizontal hydraulic pipe bending cylinder 2 completes after reset operation, can enter again pushing tow operation next time, so repeatedly, thereby realizes walking pushing tow. According to the needs of pushing tow operation, can strengthen the return stroke of horizontal hydraulic pipe bending cylinder 2, thereby improve speed and the efficiency of pushing tow operation.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this. All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
A kind of walking type pushing device based on rolling and sliding friction that the present invention provides, simple in structure, dependable performance, has stronger practicality and higher economy.
