Abstract
The invention discloses a wedge-shaped pressing structure of a lower guide plate in a cross head of a drilling pump. The wedge-shaped pressing structure comprises a plurality of guide plate supports, a base plate and a machine frame front cross wall board, wherein the multiple guide plate supports, the base plate and the machine frame front cross wall board are coaxially sequentially arranged on a machine frame support. A wedge-shaped check block is fixed to the two guide plate supports at the rear end. A downward lower shoulder is arranged at the front end of the wedge-shaped check block. An upper shoulder is arranged upwards at the rear end of the wedge-shaped check block. Two bosses provided with inclined faces are arranged on the inner surface of the upper shoulder. The two bosses are clamped in inclined-face steps at the rear end of a lower guide plate. A front end wedge-shaped support is installed on the upper surface of the base plate. Two wedge-shaped tables are symmetrically fixed to the upper surface of the front end wedge-shaped support. The portions, closely adjacent to each other, at the rear sides of the two wedge-shaped tables are each provided with a wedge-shaped pressing block. Each wedge-shaped pressing block is provided with a front wedge-shaped face and a rear wedge-shaped face, and the front wedge-shaped face and the rear wedge-shaped face of each wedge-shaped pressing block are in contact with the wedge-shaped table of the front end wedge-shaped support and a wedge-shaped groove of the lower guide plate respectively. The wedge-shaped pressing structure is easy and convenient to replace and operate.

Incline bench clamping；Two location-plates 24 are provided between backing plate 5 and adjacent guide plate bearing 3, are passed through in the upper surface of backing plate 5
Two housing screws 1 are provided with front end wedge shape bearing 8, and cross wall plate 6 holds out against before the front end face of front end wedge shape bearing 8 and frame；
See Fig. 4, front end wedge shape bearing 8 is movable component, the upper surface of front end wedge shape bearing 8 is symmetrically fixedly installed two wedges
Shape platform 16, in the rear side immediate vicinity of two wedge shape platforms 16 a wedge shape briquetting 9 is respectively arranged with, and wedge shape briquetting 9 is detachable
Part, each wedge shape briquetting 9 is provided with before and after lozenges, respectively with the wedge shape platform 16 of front end wedge shape bearing 8 and the wedge shape of bottom guide 12
Groove is contacted；
Each wedge shape briquetting 9 is connected by housing screw 2 11 and supporting spring washer 10 with front end wedge shape bearing 8,
Wedge shape briquetting 9 is set to wedge between front end wedge shape bearing 8 and the rear end face of bottom guide 12 by tightening housing screw 2 11；Due to wedge shape
Two boss 15 of block 14 are stuck on the rear end incline bench of bottom guide 12, wedge shape briquetting 9 wedge the wedge-shaped slot of bottom guide 12 with it is front
Hold between wedge shape bearing 8, and then realize axial restraint and the clamping of the rear and front end to bottom guide 12；
See Fig. 5, mounting hole is provided with wedge shape briquetting 9, the stub end of housing screw 2 11 is placed in the mounting hole so that wedge
Shape briquetting 9 can do the axial movement of certain distance with housing screw 11, when housing screw 11 compresses wedge shape briquetting 9, due to wedge
The locking effect of shape, and then bottom guide 12 can be compressed and locked；
See Fig. 6, be engaged with aforesaid structure, bottom guide 12 is set to without shoulder structure, in its front end wedge-shaped slot is provided with,
Incline bench is machined with its back-end so that the front and back end of bottom guide 12 constitutes respectively different from wedge shape briquetting 9 and wedge-shaped catch 14
Wedge mechanism, front and back end is respectively adopted different wedge shapes and compresses modes, by tightening the voussoir housing screw of front end two, realizes
Bottom guide 12 is carried out axial and circumferentially fixed.
The wedge shape compressing structure of the present invention, implements to install according to following steps：
First, the installation process of crosshead bottom guide 12
Step 1, installation guide plate bearing 3：Arrangement of the guide plate bearing 3 on frame bearing 1 as shown in Figure 2 (can be as needed
The quantity of guide plate bearing 3 is set, and the embodiment of the present invention is four)；
Step 2, the wedge-shaped catch 14 for installing rear end：Wedge-shaped catch 14 is first placed on two guide plate bearings 3 of rear end
On arc surface, location-plate 2 is put in two lower surface channels of guide plate bearing 3 of rear end, then by housing screw 3 13 and calmly
Position plate 2 is fixed and clamped wedge-shaped catch 14 on arc surface, the lower shoulder and the end of a guide plate bearing 3 due to wedge-shaped catch 14
Face is close to, therefore wedge-shaped catch 14 can bear the active force mobile to the back-end of bottom guide 12, such as Fig. 1, Fig. 3；
Step 3, installation bottom guide 12：Bottom guide 12 is lain in a horizontal plane in into wedge-shaped catch 14 and the guide plate bearing 3 of front end two
On, two boss 15 of wedge-shaped catch 14 are stuck in into the rear end inclined-plane of bottom guide 12, rear end wedge mechanism is so cooperatively formed, such as scheme
6；
Step 4, front end wedge shape bearing 8 is installed：In Fig. 4, two through holes are for the connection with backing plate 5, two housing screws 7
Front end wedge shape bearing 8 is fixedly mounted on the backing plate 5 of frame bearing 1 through respective through hole, by the front end face of front end wedge shape bearing 8
With the dieback of cross wall plate 6 before frame, it is double that two wedge shape platforms 16 and the front end wedge-shaped slot of bottom guide 12 of front end wedge shape bearing 8 form front end
Wedge structure；
Step 5, fix to clamp bottom guide 12：In Fig. 4, two screws are used to install the housing screw 2 11 of wedge shape briquetting 9,
Two wedge shape briquettings 9 are arranged in the double wedge structure that front end wedge shape bearing 8 is constituted with bottom guide 12, by spring washer 10
Wedge shape briquetting 9 is pressed in wedge-shaped slot with housing screw 2 11, housing screw 2 11 is located in the mounting hole of wedge shape briquetting 9；Together
When, the rear end inclined-plane of bottom guide 12 forms wedge shape attachment structure with two boss 15 of wedge-shaped catch 14；Finally, by tightening compression
Screw 2 11 makes wedge shape briquetting 9 drive bottom guide 12 to be tightly secured on guide plate bearing 3, due to the self-locking of front and back end wedge structure
And the elastic deformation effect of spring washer, bottom guide 12 is not produced in crosshead running axially and is circumferentially slided.
2nd, in maintenance process crosshead bottom guide 12 assembly and disassembly methods
When needing to change bottom guide 12, the 7-part of part 11 in such as Fig. 1 is pulled down first, crosshead is retreated to into rear limit
And be lifted up (can also be in other positions) so as to depart from and formed gap with the inner arc surface of bottom guide 12, under then passing through
The screw hole of the front end of guide plate 12 pulls out the macropore of cross wall plate 6 before its Jing frame；With same method, lead in the case where crosshead is retreated to
The rear limit of plate 12 and it is lifted up, is shifted onto the macropore of cross wall plate 6 before its Jing frame by the screw hole of the front end of bottom guide 12
On guide plate bearing 3, then clamping is fixed to bottom guide 12 by above-mentioned steps 4 and step 5, see Fig. 7.
