Description

Detachably beam type mobile drill charger

Technical field

This utility model belongs to mechanical equipment technical field, relates to one detachably beam type mobile drill and adds Carry and put.

Background technology

The rig that the oil-well rig designed first specially requires with user, it is necessary to carry out the load examination of rig Testing, test load is the specified maximum load of rig.

At present, grade beam churn charger is due to cheap, and simple in construction, is rig load test A kind of modal testing equipment in field, applies to load to rig substructure by the retraction of oil cylinder, ground beam type There is following characteristics: owing to the rig substructure of ground beam type test well mouth will be by load upwards when load test Load forces, for avoiding the stress of base to concentrate, therefore it is required that the contact area of grade beam and base is the bigger the better. The carrier bar of ground beam tester is typically middle narrow, and both sides are to increase the ratio that the contact area with base is done Wider, general width is at least more than 5 meters, and whole grade beam becomes dumbbell shaped；The oil cylinder loaded crouches at ordinary times Being placed in melt pit, when load test, oil cylinder is propped up and is placed on upright position.

In view of the feature of ground girder structure, traditional ground girder structure is by dumbbell structure and load cylinder Impact can not make movable type charger.The use time average one bench drill machine of charger is only There is time half a day, and the assembling test period of a bench drill machine was up to about two months, took test well head Time is oversize, causes the waste of test resource, and other test rig can only be waited in line.

Utility model content

The purpose of this utility model is to provide one detachably beam type mobile drill charger, solves In prior art beam type load testing machine move difficulty, the utilization rate of rig load test device is low, The problem that equipment cost is high.

This utility model be employed technical scheme comprise that, one detachably beam type mobile drill adds and carries Put, including be fixed on edge on well head tunnel bearing and in tunnel the grade beam of movement, grade beam two ends are respectively Being provided with an air hoist, two air hoists are connected with grade beam two ends by cable wire respectively；

Described grade beam is detachable structure, the beam I symmetrical including both sides along the longitudinal centerline and beam II； Beam I and beam II is arranged on cylinder support both sides by multiple bearing pins respectively, by many between beam I and beam II Group connects the fixing connection of otic placode, is provided with oil cylinder at cylinder support upper surface.

Detachably beam type mobile drill charger of the present utility model, is further characterized in that:

Oil cylinder is retracted to be less than during the end upper surface of grade beam.

The beneficial effects of the utility model are, load testing machine is divided into mobile grade beam 2 and hold-down support 1 two parts, bearing 1 makes the position being fixedly mounted to each test well head, the mobile employing of grade beam 2 Air hoist 3 both sides pull, and grade beam 2 slides on slide rail 4, can pass through when moving for ease of grade beam 2 Below bearing 1, load cylinder 7 not above grade beam 2 above, when otherwise moving with bearing interfere. It is thus desirable to load in grade beam 2 by oil cylinder 7, for this, grade beam 2 is made the ground girder construction of fractionation.Specifically Feature includes:

1) meet a set of charger multiple stage rig is loaded, save the construction cost of testing stand.

2) be arranged on traditional oil cylinder grade beam above compared with, reduce the setting height(from bottom) of oil cylinder, During rig load test, the height after oil cylinder is holded up also has substantial degradation, it is simple to oil cylinder head connects examination Test elevator, decrease the degree of depth of melt pit needed for grade beam.

Detailed description of the invention

With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.

With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is, including being fixed on edge on well head tunnel Bearing 1 and in tunnel the grade beam 2 of movement, bearing 1 fixed placement at each pressure testing well head to expand ground Beam 2 and the contact surface of rig pedestal；Grade beam 2 passes through tunnel (geosyncline) according to the load test demand of rig Move to each test well head, thus realize a set of load test device test multiple stage rig；Grade beam 2 two ends Being respectively arranged with an air hoist 3, two air hoists 3 are respectively by cable wire with grade beam 2 two ends even Connecing, the cooperation that pulls being moved horizontally through two 5t air hoists 3 of grade beam 2 realizes；

With reference to Fig. 4, Fig. 5, grade beam 2 is detachable structure, including the symmetry of both sides along the longitudinal centerline Beam I8 and beam II9；Beam I8 and beam II9 is arranged on cylinder support 6 both sides, beam by multiple bearing pins respectively Connect by many group connection otic placodes 5 are fixing between I8 and beam II9, be provided with at cylinder support 6 upper surface Oil cylinder 7.

When rig charger moves, beam I8 and beam II9 slides on bottom surface, tunnel slide rail 4.

(it is in low level and is referred to as sleeping dress) the upper table less than grade beam 2 when oil cylinder 7 is retracted to the end, it is simple to grade beam The movement of 2, during rig load test, holds up oil cylinder 7.

When grade beam 2 assembles, with beam I for assembling benchmark, first oil cylinder 7 is arranged on cylinder support 6 It is assembled into cylinder support assembly together, then cylinder support assembly is arranged on beam I, back rest II fills, Otic placode (using single bi-lug plate connected mode) between beam I with beam II is connected with latch.

Work process of the present utility model is:

Step 1: bearing 1 is arranged on each test well head, then by each rig needing to load according to this work Skill requires to be completed in each test well position, is ready for load test.

Step 2: start air hoist 3, is dragged to first well head needing test, oil cylinder 7 by grade beam 2 Prop up, carry out the load test of rig.

Step 3: after first test well oral examination has been tested, carry out the test of other well head successively.

Operation principle of the present utility model is:

This load testing machine is divided into mobile grade beam 2 and hold-down support 1 two parts, and grade beam 2 is in tunnel Mobile, the position being fixedly mounted to each test well head made by bearing 1.For ease of movement, load cylinder Grade beam 2, not above the upper surface of grade beam 2, is made detachable ground girder construction for this by 7, and oil cylinder is pacified It is contained in grade beam, thus reduces the setting height(from bottom) of oil cylinder 7, workmen when facilitating rig load test Operation.Grade beam 2 uses air hoist 3 both sides to pull movement, can realize utilizing a bench drill machine to add and carry Put and multiple stage rig is carried out load test, thus improve the utilization rate of loading equipemtn, decrease testing stand Repeated construction.
