Description
Technical field
The utility model relates to a kind of tumble gate trolley automatic stem pulling structure.
Background technology
Generally tumble gate can be used in occasions such as warehouses, conventional electric tumble gate is powered, trolley is curved track, in curved rail walking, current-collector easily occurs that electrical power contact is unstable, generation drag chain or cable directly draw the operation jam that current-collector causes, the phenomenon such as electric wire, cable breakdown that long-time current-collector discontinuity causes, thus affect the normal operation of tumble gate.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of avoiding directly to draw by drag chain or cable the operation jam that current-collector causes, can ensure the tumble gate trolley automatic stem pulling structure that tumble gate smoothness is run.
The purpose of this utility model is achieved through the following technical solutions: a kind of fixed point Onoff pole jack of trolley, comprise trolley, current-collector, drive block, positive stop and callback device, clamping plate are provided with outside described current-collector and driving block, described current-collector slides in trolley, fixed head is provided with in the upper end of described trolley, described positive stop is connected with fixed head by connecting axle, described callback device is connected on door leaf by base, described driving block is connected on callback device, described callback device comprises U-shaped driving lever and connecting ring, described U-shaped driving lever is connected with base by connecting ring, described U-shaped driving lever is provided with cross bar, described cross bar is connected with one end of extension spring, the other end of described extension spring is fixed on door leaf.
The advantage that the utility model compared with prior art has is: structure is simple, reasonable in design, easy for installation, has ensured uniform force and the stable operation of current-collector, thus be convenient to tumble gate operation, that tumble gate is run is more smooth.
accompanying drawing illustrates:
Fig. 1 is right view of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the structural representation of callback device;
Number in the figure: 1-comprises trolley, 2-current-collector, 3-driving block, 4-extension spring, 5-clamping plate, 6-base, 7-U type driving lever, 8-connecting ring, 9-cross bar, 10-positive stop, 11-fixed head, 12-connecting axle.
detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
A kind of embodiment of the fixed point Onoff pole jack of a kind of trolley of the utility model is shown: comprise trolley 1 as Fig. 1-3, current-collector 2, drive block 3, positive stop 10 and callback device, clamping plate 5 are provided with outside described current-collector 2 and driving block 3, described current-collector 2 slides in trolley 1, fixed head 11 is provided with in the upper end of described trolley 1, described positive stop 10 is connected with fixed head 11 by connecting axle 12, described callback device is connected on door leaf by base 6, described driving block 3 is connected on callback device, described callback device comprises U-shaped driving lever 7 and connecting ring 8, described U-shaped driving lever 7 is connected with base 6 by connecting ring 8, described U-shaped driving lever 7 is provided with cross bar 9, described cross bar 9 is connected with one end of extension spring 4, the other end of described extension spring 4 is fixed on door leaf.
The utility model is by current-collector and drive the inside and outside two clamping plates of block to clamp, current-collector slides in trolley, sliding of current-collector is driven by driving lever during door leaf walking, move to positive stop place, because U-shaped driving lever is connected with base by connecting ring, for being flexibly connected, so when U-shaped driving lever automatically offsets downward and drives block to depart from, current-collector runs stop motion; When door leaf inverted running, U-shaped driving lever realizes automatically reseting by extension spring, continues to drive sliding of current-collector.
The utility model structure is simple, reasonable in design, easy for installation, solve the electrical power contact instability that tumble gate easily occurs in curved rail walking, drag chain or cable phenomenon occur, solve the operation jam that directly traction current-collector causes, can be good at ensureing that current-collector normally runs, tumble gate is run more smooth, decrease maintenance rate, improve the competitiveness of product.
