A vehicle-mounted drilling rig like a well drilling rig, a coal bed gas drilling rig, or a fossil oil drilling rig and the like equipped with the box with the pump has the advantages of small output power loss and big torsion, and can drive a chassis.

Description

The band pump box

Technical field

The utility model relates to vehicular all-hydraulic drill technical field, thereby specifically is a kind of device that drives hydraulic pump from the power taking of carrier loader chassis.

Background technology

Water drilling rig, coal bed gas rig, oil-well rig etc. adopt hydraulic-driven, have the all-hydraulic stepless speed regulation of energy, and rotating speed and moment of torsion adjusting range are big, and technology adapts to strong advantage, has become a kind of trend at present.Hydraulic system then needs Appts. having pump to drive hydraulic pump provides power, and known technology generally is to adopt power takeoff by the carrier loader engine torque extraction, and Appts. having pump connects with power takeoff, the rotating band pump installation.This Appts. having pump exists the power output loss big after connecting power takeoff, the shortcoming that output torque is little.

The utility model content

The purpose of this utility model provides a kind of band pump box, and it is little to have a power output loss, the advantage that output torque is big, and have the function that drives the chassis.

The technical solution adopted in the utility model is:

A kind of band pump box, adopt the gear form, it is characterized in that: comprise power shaft, output shaft, band pump shaft one, band pump shaft two, band pump shaft three, power shaft, band pump shaft one, band pump shaft two, band pump shaft three be arranged in parallel from bottom to up successively, on power shaft, band pump shaft one, band pump shaft two, the band pump shaft gear is installed respectively and is constituted three grades of parallel transmissions of cylindrical gear pair, output shaft and power shaft are coaxially set, and power shaft is equipped with can be realized that power shaft cogs and cog engagement or the fork that breaks away from is hung and closed mechanism with pump shaft one; The fork extension that can be connected or break away from power shaft is installed on the output shaft closes mechanism, power shaft links to each other with the output shaft of gear-box of carrier loader motor.

Operating principle:

Band pump box power shaft is connected with the engine mission output shaft, carries engine torque extraction from the chassis carrier loader, during driving, the output shaft extension is closed mechanism's extension close, power shaft is hung closed mechanism's disengagement simultaneously, by the output shaft outputting power, output shaft is connected with carrier loader drive axle power transmission shaft, realizes that driving drives; When rig moves to the well site and will carry out drillng operation, the output shaft extension is closed mechanism throws off, simultaneously extension on the power shaft being closed mechanism's extension closes, band pump shaft one, band pump shaft two, band pump shaft three obtain power by the transmission of three grades of cylindrical gear pairs, drive and its hydraulic pump that is connected, thereby provide service for the rig operation.

Beneficial effect:

The utility model is directly from the engine mission power taking of carrier loader self, close mechanism and output shaft is hung the operation of closing mechanism by hanging on the power shaft, realized the switching of driving function and drillng operation function, vehicle-mounted churns such as water drilling rig, coal bed gas rig, oil-well rig dispose this band pump box, reduce the power output loss, improved output torque.The utility model is applicable to the repacking of various truck chassis.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is that Fig. 1 is along the A-A sectional view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As Fig. 1, shown in Figure 2, the band pump box adopts the gear form, power shaft 1, output shaft 6, band pump shaft 1, band pump shaft 2 11, band pump shaft 3 13 be arranged in parallel from bottom to up successively, each is installed on the casing 15 by bearing, power shaft 1, band pump shaft 1, band pump shaft 2 11, on the band pump shaft 3 13 gear 3 is installed respectively, gear 10, gear 12, gear 14, four gear three grades of parallel transmissions of cylindrical gear pair of engagement formation in twos successively, output shaft 1 is equipped with the fork extension and closes mechanism, fork is hung and closed mechanism is the gear common mechanism, by being installed in the external toothing 4 that output shaft 1 cooperatively interacts, ring gear 5, the external tooth 3a that is provided with on the gear 3, the fork (not shown) constitutes, and between gear 3 on the output shaft 1 and the power shaft 1 bearing is installed.External tooth 3a and external toothing 4 on the gear 3 are set up in parallel.Output shaft 6 is coaxially set with power shaft 1, be equipped with on the output shaft 6 and can realize that closing the fork extension that is connected or breaks away from connection with power shaft 1 extension closes mechanism, this extension closes the external tooth 6a that external tooth 1a that mechanism has by power shaft 1 axle head and output shaft 6 axle heads have, and slidably being enclosed within ring gear 7, the fork (not shown) formation that external tooth 1a, external tooth 6a go up engagement, this structure is the known technology of using always equally.

Power shaft 1 input is connected with flange 2, and power shaft 1 is connected with the engine mission output shaft by flange 2 and power transmission shaft.Output shaft 6 outputs are connected with flange 8, and output shaft 6 is by flange 8 outputting powers, and flange 8 is connected with carrier loader drive axle power transmission shaft, drive the chassis walking.Band pump shaft 1, band pump shaft 2 11, band pump shaft 3 13 can connect each hydraulic pump, for rig operation hydraulic system provides power.

Stir on the output shaft 6 and to hang the ring gear 7 that closes mechanism and be moved to the left, external tooth 1a on ring gear 7 and the power shaft 1 and the external tooth 6a on the output shaft 6 are meshed simultaneously, output shaft 6 is hung and is closed mechanism and be in to hang and close the position, realizes that power shaft 1 is connected with output shaft 6; Stir simultaneously on the power shaft 1 and to hang the ring gear 5 that closes mechanism and move to left and be in and external toothing 4 positions of engagement, hang on the power shaft 1 and close mechanism and be in disengaging and do not hang and close the position, gear 3 is because buried bearing, therefore be in idling conditions, under this state, power shaft 1 transferring power is given output shaft 6, and output shaft 6 and then outputting power drive chassis and travel.Otherwise, stir ring gear 7 and move right, make ring gear 7 and power shaft 1 external tooth 1a break away from engagement; Stirring ring gear 5 simultaneously moves right, external tooth 3a on ring gear 5 and external toothing 4 and the gear 3 is meshed simultaneously, power shaft 1 transferring power is given gear 3, and by three grades of parallel transmissions of cylindrical gear pair, make band pump shaft 1, band pump shaft 2 11, band pump shaft 3 13 equal outputting powers, drive hydraulic pump works.The quantity of band pump shaft can optionally design.
