Description

A kind of scaffold

Technical field

The utility model belongs to construction clothing arts, more particularly to a kind of scaffold.

Background technology

Scaffold is to ensure workbench that each work progress is smoothed out and sets up.Position by setting up is divided into outer Scaffold, internal scaffolding；It can be divided into timber scaffolding, bamboo scaffolding, steel pipe scaffold by material difference；It is divided by structural form vertical Rod-type scaffold, bridge scaffold, swinging scaffold, suspended scaffold, choose formula scaffold, climb formula foot hand door-type scaffold Frame.

Existing scaffold includes supporting rack and the backing plate being positioned on supporting rack, is provided in supporting rack bottom with brake The idler wheel of vehicle component can so realize the movement and fixation of scaffold, be disadvantageous in that：It is if muddy or loose in road When constructing on soft ground, since the contact area on idler wheel and road surface is small, easily scaffold is made to be absorbed in ground, so that entire foot There is unstable situation in hand cradle, is prone to accidents, therefore has improved space.

Utility model content

The purpose of this utility model is to provide a kind of scaffold, can work on soft road surface.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of scaffold, including supporting rack and the backing plate being positioned on support frame as described above, support frame as described above includes several A leg, the feet bottom are provided with moving assembly, and the moving assembly includes storage case, moves block, screw and directive wheel； The storage case bottom end opening and top are fixedly connected on the bottom of the leg, and described screw one end is laterally movable to be arranged in appearance Receive the one side of case, the other end overhangs to outside storage case；The shifting block activity be positioned in the storage case and thread fitting in Screw, the shifting block is connected with several leads compared with the two sides of the screw, described to accommodate on chamber interior wall Offer the guide groove for the oblique movement of the lead；Offer what is moved up and down for the screw on the storage case side wall Slip hole, the directive wheel are connected to the bottom of the shifting block.

Using the above program, when standing on to scaffold on ground, it can be driven by rotary screw rod and move block and directive wheel edge Screw length direction moves, then makes shifting block and directive wheel are oblique together to move into receiving by the cooperation of lead and guide groove Case；When scaffold is stood on ground, storage case bottom is contacted with ground, be compared to idler wheel in existing scaffold directly with For the point contact of ground, the contact area on storage case and ground is larger, can stablize in miriness or on soft ground Construction, improves security.

Preferably, the guide groove includes inclined guide groove, cross connection is oriented in the first of the inclined guide groove upper and lower side respectively Slot and the second guide groove, first guide groove and the second guide groove are located at the both sides of the inclined guide groove.

Using the above program, the setting of the first guide groove and the second guide groove can will move block and smoothly place, and improve and stablize Property.

Preferably, the first guiding groove bottom is provided with the first downward concave surface, and the second guide groove top surface is set There is the second upward concave surface.

Using the above program, the setting of the first concave surface and the second concave surface can increase the contact surface of lead and guide groove Product makes shifting block more stablize.

Preferably, the storage case bottom is connected with rubber pad.

Using the above program, during construction, rubber pad helps to stand on scaffold on ground, plays anti-skidding effect, carries The high stability of scaffold, so as to improve security.

Preferably, the storage case bottom is provided with to close the sealing plate of storage case opening.

Using the above program, when construction, directive wheel is withdrawn in storage case, and sealing plate can seal storage case bottom end opening It closes, when constructing on soft ground, the setting of sealing plate helps to increase the contact area on storage case bottom surface and ground, into One step adds the stability of scaffold, moreover it is possible to play the role of protection to directive wheel.

Preferably, the directive wheel is universal wheel.

Using the above program, by the way that directive wheel is arranged to universal wheel, make scaffold movement flexible.

Preferably, restraining position ring block, the spacing ring and the receiving chamber interior wall phase are fixedly connected on the screw periphery It contradicts.

Using the above program, restraining position ring block is fixedly connected on periphery on screw, can prevent screw from taking off when rotated Separate out storage case.

Preferably, the outboard end of the screw has been wholely set cylindric handshake part and has been provided on its periphery anti-skidding Lines.

Using the above program, the setting of handshake part facilitates worker with hand-drive screw, and the setting of non-slip texture helps to increase Add the frictional force between hand and handshake part periphery, make to skid during rotation, improve efficiency.

In conclusion the utility model has the advantages that：

1. the scaffold can on soft ground safe construction.

2. by setting rubber pad and sealing plate that can further improve the security performance of scaffold in storage case bottom.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of scaffold disclosed in the present embodiment can construct on the muddy or soft ground of some roads.

As shown in Figure 1, a kind of scaffold, including supporting rack 1 and the backing plate being positioned on supporting rack 12, supporting rack 1 wraps Several legs 11 are included, 11 bottom of leg is provided with moving assembly 3.

As shown in Figure 2, Figure 4 shows, moving assembly 3 includes storage case 31, moves block 32, screw 33 and directive wheel 34.Storage case 31 is opening down and top is fixedly connected on the bottom of leg 11, and one side offers vertical slip hole 311, storage case 31 Cover board 313 is provided on one side compared with slip hole 311, cover board 313 is bolted to connection with storage case 31.

One end of screw 33 is laterally movable to be arranged in slip hole 311, and the other end overhangs to storage case 31 outside and at the end one Body is connected with handshake part 331, handshake part 331 is cylindrical and periphery on offer non-slip texture 3311, the outer circle of screw 33 Restraining position ring block 332 is fixedly connected on face, spacing ring 332 and 31 inner wall of storage case are inconsistent, make the nothing in storage case 31 of screw 33 Method does transverse movement.

It moves 32 activity of block to be positioned in storage case 31 and be flexibly connected with the screw thread of screw 33, moves block 32 compared with screw 33 Two sides on be connected with two leads 321, two leads 321 are corresponded in storage case 31 in horizontally disposed The guide groove 312 for being matched with lead 321 is offered on inner wall, makes shifting block 32 that can be moved along guide groove 312.

As shown in figure 3, guide groove 312 includes inclined guide groove 3121, cross connection is in the of 3121 upper and lower side of inclined guide groove respectively One guide groove 3122 and the second guide groove 3125, the first guide groove 3122 and the second guide groove 3125 are located at the two of inclined guide groove 3121 Side, 3122 bottom surface of the first guide groove are provided with the first downward concave surface 3123, and 3125 top surface of the second guide groove is provided with upward Second concave surface 3124, the first concave surface 3123 and the second concave surface 3124 cooperate with the periphery of lead 321 and contradict.

As shown in Figure 2, Figure 4 shows, directive wheel 34 is universal wheel, is bolted to connection in the bottom for moving block 32, when shifting block 32 when moving obliquely, and directive wheel 34 can be fully seated in storage case 31.
