Abstract
A nylon board replacing device of a horizontal directional drilling machine is used in the technical field of horizontal directional drilling machine installation and maintenance. According to the nylon board replacing device of the horizontal directional drilling machine, a nylon board is installed between a power head box body and a guide rail surface. The nylon board replacing device of the horizontal directional drilling machine is characterized in that jacking mechanisms are installed on the four symmetrical corners of a base board of the power head box body, the jacking mechanisms are four screws which are screwed on the base board of the power head box body, the upper portion of each screw is of a multi-surface structure, and the jacking mechanisms can also be lead screws or jacks. When the nylon board needs to be replaced, the whole power head box body can be supported by means of the strength of four bolts which are lifted, and then the nylon board can be replaced fast, conveniently and safely. Due to the arrangement of the screws with a supporting function on the four corners of the base board of the power head box body, labor intensity of operators is relieved, the replacement of the nylon board is more convenient and faster, extra cost caused by the use of a crane is reduced, equipment maintaining cost is saved, and time for maintaining is shortened.
Description
Technical field
The utility model relates to horizontal directional drilling machine I﹠M technical field, is more changing device of a kind of horizontal directional drilling machine nylon back plate specifically.
Background technology
In the work progress of horizontal directional drilling machine, unit head (dolly) moves on raceway surface, orbital plane is not only being born the gravity of unit head, but also bearing due to pull-back force and the caused extruding force of rotary torque, if the lower plane of unit head is directly contacted with orbital plane, will produce very large destructive power to orbital plane, this is very uneconomic, therefore all the high-strength abrasion-proof nylon sheet can be installed between relative slide plane.As shown in Figure 5, sequence number 5 is the unit head casing; Sequence number 6 is upper nylon sheet; Sequence number 7 is backing plate; Sequence number 8 is track body; Sequence number 9 is lower nylon sheet; Sequence number 10 is baffle plate.Because stress condition is more abominable, there is the mixture of lubrication oil and earth unavoidably in the surface that adds track body 8, so the wearing and tearing of nylon sheet are relatively or than faster, and the upper nylon sheet 6 in Fig. 5 especially.And along with the wearing and tearing of nylon sheet increase the weight of; the center line of the main shaft of unit head casing 5 will cause drilling rod to break away from the center of the place ahead clamper relatively near guide pass, changes the drilling rod stress; accelerate drill rod abrasion, even cause the failure fracture of unit head protection short circuit.Therefore, the upper nylon sheet 6 in Fig. 5 and upper nylon sheet 9 will often be changed.But because unit head is all heavier, little of the hundreds of kilogram, arrive greatly several tons, cause exchanging for of nylon sheet very inconvenient, even have to so hanging device is provided, increased the maintenance cost of equipment, also increased and safeguarded duration.
Summary of the invention
For overcoming the more deficiency of changing device of existing level Directional Drilling nylon back plate, invention order of the present utility model is to provide more changing device of a kind of horizontal directional drilling machine nylon sheet,, with conveniently replaced nylon sheet, improves the maintainability of equipment.
For achieving the above object, between unit head casing of the present utility model and guide pass, nylon sheet is housed, it is characterized in that: symmetrical four jiaos are equipped with jacking mechanism on the base plate of unit head casing; Jacking mechanism is four screws, and four screw threads are on the base plate of unit head casing, and the top of screw is multi-plane structure; Jacking mechanism is leading screw or jack.
When needs were changed nylon sheet, only need rotate four bolts, use the strength of four bolts and just can prop up whole unit head casing, thereby change nylon sheet rapidly, and were both convenient, also safety.
The utility model compared with prior art, by four jiaos of the base plates at the unit head casing, passive screw is installed, reduced operating personnel's labour intensity, make and change the nylon sheet more convenient and quicker, reduced due to the cost that uses loop wheel machine to increase, the maintenance cost of also having saved equipment simultaneously, shortened and safeguarded duration.

The specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, between unit head casing 1 and guide pass 3, nylon sheet 2 is housed, symmetrical four jiaos are equipped with jacking mechanism on the base plate of unit head casing 1, jacking mechanism is four screws 4, the top of screw 4 is for ease of the multi-plane structure of rotation, four screws 4 are spun on the base plate of unit head casing 1, and jacking mechanism also can be leading screw or jack.
When needs are changed nylon sheet 2, only need to twist four bolts 4, use the strength that four bolts 4 withstand guide pass 3 and just can prop up whole unit head casing 1, thereby change rapidly nylon sheet 2, both convenient, also safety.
