Description
Technical Field
The utility model belongs to a rig fixing device.
Background
At present, a cast-in-place pile construction machine mostly adopts a rolling steel pipe as a rolling shaft of a pile machine walking track to walk, and the lower end of the rolling steel pipe is not only in unlimited contact with the pile machine walking track but also cannot be fixed on the pile machine walking track. Therefore, after the pile machine is positioned for drilling, the pile machine body vibrates greatly, and the lower part of the machine body is an unfixed rolling steel pipe, so that the integral sliding deviation of the pile machine is easy to cause, the deviation of pile holes is increased, and the pile forming verticality is influenced.
Disclosure of Invention
The utility model aims at designing a rig fixing device, can realize quick fixed of stake machine lower part roll steel pipe on stake machine walking track, have simple structure, fixed firm, the working property is reliable, the flexible operation is laborsaving, extensive applicability and convenient to use's advantage.
Therefore, the utility model discloses a tension spring. The bottom end surfaces of the two rolling shaft cushion blocks are planes, and the corresponding inner end surfaces of the two rolling shaft cushion blocks are semi-circular arc surfaces. The bottom end surfaces and the semi-circular arc surfaces of the roller bearing cushion blocks are provided with anti-skidding rubber sheets, the connecting pull rod is in an inverted U shape, the two ends of the connecting pull rod are respectively connected with the middle parts of the upper end surfaces of the two roller bearing cushion blocks into a whole, and a tensioning spring is arranged between the middle parts of the two posts of the connecting pull rod.
The inner end surface of the rolling shaft cushion block is a semi-circular arc surface, and the radian of the semi-circular arc surface is the same as the peripheral radian of the rolling steel pipe. The connecting pull rod is made of flat steel.
The device achieves the purpose of the utility model.
The utility model discloses can realize quick fixed of stake machine lower part roll steel pipe on stake machine walking track, have simple structure, it is fixed firm, the working property is reliable, the flexible operation is laborsaving, extensive applicability and convenient to use's advantage.
Compared with the prior art, the utility model has the following advantages and positive effects:
(1) the utility model discloses processing simple manufacture, the cost of manufacture is low, easily carry the operation, recoverable, easy restoration.
(2) The utility model discloses a rubber piece is established to the bottom and the semicircle face of roller bearing cushion, has better increase frictional force, reinforces the steel pipe fastening effect that rolls.
(3) The utility model discloses can step up automatically on rolling steel pipe both sides in stake machine walking track, realize quick fixed, need not the manual work and take other measures, easy operation.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the usage state of the present invention.
Detailed Description
As shown in fig. 1 and 2, a drill fixing device includes a tension spring 3. The bottom end surfaces of the two roller cushion blocks 1 are planes, and the corresponding inner end surfaces of the two roller cushion blocks are semi-circular arc surfaces. The inner end surface of the rolling shaft cushion block is a semi-circular arc surface, and the radian of the semi-circular arc surface is the same as the peripheral radian of the rolling steel pipe.
The bottom end face and the semi-circular arc face of the rolling shaft cushion block are fixed with anti-skid rubber sheets 2 in a fixing mode such as gluing. The anti-skid rubber sheet is a product sold in the market. The rolling shaft cushion block is formed by welding a wood block wrapped with a thin iron skin plate or a steel plate with the thickness of 5-10 mm. The width of the rolling shaft cushion block is 10-30 cm.
The connecting pull rod 5 is in an inverted U shape and is made of flat steel with the thickness of 2mm and the width of 3 cm. The two ends of the connecting pull rod are respectively connected with the middle parts of the upper end surfaces of the two rolling shaft cushion blocks into a whole through welding. A tension spring 3 is arranged between the middle parts of the two posts connecting the pull rod. The drag hooks 4 at the two ends of the tension spring are fixedly pulled on the middle parts of the two posts of the connecting pull rod. When the tension spring is tightened, the corresponding inner end surfaces of the two rolling shaft cushion blocks are mutually supported.
When the quick fixing device is used, the two rolling shaft cushion blocks are pulled apart by a distance (the tension spring extends to store force) and are placed on two sides of the rolling steel pipe 6 on the pile machine walking track 7, the pulling force is released, the tension spring contracts, the two sides of the rolling steel pipe 6 are tightened by the semi-circular arc surfaces of the two rolling shaft cushion blocks, the lower ends of the two rolling shaft cushion blocks are located on the pile machine walking track, and the quick fixing of the rolling steel pipe on the pile machine walking track is completed. The utility model discloses there is better increase frictional force, strengthens the steel pipe fastening effect that rolls, has realized the drilling in-process rig overall stability, and the pile hole vacancy deviation that causes is rocked because of the rig to the significantly reduce.
In a word, the utility model discloses can realize quick fixed of stake machine lower part roll steel pipe on stake machine walking track, have simple structure, it is fixed firm, the working property is reliable, the flexible operation is laborsaving, extensive applicability and convenient to use's advantage, convenient to popularize and use.
