Description

Special tool for disassembling floating sleeve of raise boring machine

Technical Field

The utility model belongs to the technical field of extracting tool, specific theory relates to a raise boring machine cover that floats dismantles specialized tool.

Background

The raise boring machine is the main equipment for raise boring construction, and the floating sleeve of raise boring machine is the key part for connecting the power head and the drill rod of the machine and has the core connection operation of the whole equipment to complete the drilling and reaming. In the working process, the power of the whole drilling machine is transmitted to the drill rod through the drilling machine, so that the floating sleeve, the drill rod and the power head can move relatively, the borne torque and abrasion are large, and when the abrasion of the floating sleeve reaches a certain degree or an aging period, the floating sleeve needs to be detached, repaired and maintained in time.

The main mode that the floating sleeve of the present raise boring machine is dismantled is: when the equipment does not work, the equipment is directly disassembled by the chuck of the equipment, and when the raise boring drill works, the chuck needs to clamp the drill rod to prevent the drill rod from falling off due to the installation of the cutter head and the drill rod below the raise boring drill. Therefore, in a traditional dismounting mode, the existing drill rod and the existing cutter head need to be dismounted firstly, the replacement is completed, and the connection are needed again, so that the progress of a construction period is seriously influenced, the connection and the dismounting of the threads of the drill rod can cause abrasion, and potential safety hazards exist to operators.

Therefore, it is necessary to provide a special tool for disassembling the floating sleeve of the raise boring machine, which avoids the abrasion caused by the joint disassembly of the drill rod and the cutter head when the floating sleeve is disassembled, reduces the labor cost and the time cost, and simultaneously reduces the safety accidents when personnel disassemble.

SUMMERY OF THE UTILITY MODEL

In order to overcome the traditional dismantlement mode of the floating cover of raise boring machine who exists among the background art and need demolish current drilling rod and blade disc earlier, change the completion and still need connect the dress again, waste time and energy, seriously influence the time limit for a project progress to, dismantle the problem that still can cause wearing and tearing to the company of drilling rod and blade disc, the utility model provides a special tool is dismantled to the floating cover of raise boring machine, dismantle the company of drilling rod screw thread when having avoided dismantling the floating cover and dismantle and cause wearing and tearing, reduced manual work and time cost, reduced the incident when personnel dismantle simultaneously.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the utility model provides a special tool for disassembling a floating sleeve of a raise boring machine, which comprises a box body 1 and a base 2; the box 1 install on base 2, establish the cavity in the box 1, the front end opening, floating cover fixed slot 3 has been seted up to the top surface, 3 size matching floating cover outlines in the floating cover fixed slot, set up the U type groove 4 that is used for the block to support the drilling rod top on the base 2, floating cover fixed slot 3 and U type groove 4 and 1 inner chamber intercommunication of box.

Preferably, a reinforcing rib 5 is arranged between the outer side of the box body 1 and the base 2.

The utility model has the advantages that:

the utility model clamps the tool into the sliding groove of the equipment through the base, thereby reducing the damage of the machine body caused by the fixing operations such as welding and the like; the inner cavity of the box body and the U-shaped groove solve the space conflict caused by the fixation of the drill rod, and the square head at the top end of the drill rod is clamped in the U-shaped groove, so that the drill rod is prevented from falling off, and the abrasion caused by the joint disassembly of the drill rod threads when the floating sleeve is disassembled is avoided; the floating sleeve fixing groove is matched with the shape of the floating sleeve, the self power of the equipment can be directly utilized for dismounting, the labor cost and the time cost are reduced, and meanwhile, the safety accidents of personnel during dismounting are reduced.

In the figure, 1-a box body, 2-a base, 3-a floating sleeve fixing groove, 4-a U-shaped groove and 5-a reinforcing rib.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in figure 1, the special tool for disassembling the floating sleeve of the raise boring machine comprises a box body 1 and a base 2; the box 1 install on base 2, establish the cavity in the box 1, the front end opening, floating cover fixed slot 3 has been seted up to the top surface, 3 size matching floating cover outlines in the floating cover fixed slot, set up the U type groove 4 that is used for the block to support the drilling rod top on the base 2, floating cover fixed slot 3 and U type groove 4 and 1 inner chamber intercommunication of box.

When the device is used for disassembling the floating sleeve, tools are embedded into the device base, the base 2 is embedded into a sliding groove of the device base, the body damage caused by fixing operations such as welding is reduced, a U-shaped groove 4 on the base 2 and an inner cavity of the box body 1 provide space for a drill rod extending from the lower part, a square head at the top end of the drill rod is matched and clamped on the U-shaped groove 4, the drill rod is ensured not to fall off, the floating sleeve is sleeved into a floating sleeve fixing groove 3, a power head is rotated by utilizing the self power of the device and is lifted, the floating sleeve can be installed and disassembled, abrasion caused by continuous disassembly of threads of the drill rod when the floating sleeve is disassembled is avoided, the floating sleeve fixing groove 3 is in a shape of the floating sleeve, the floating sleeve is ensured not to deform and slide due to overlarge stress and torque caused by unidirectional stress and torsion in the disassembly process, the power head is rotated by utilizing the self power of the device and is lifted, the assembly and disassembly are installed, abrasion of the drill rod caused by repeated disassembly is avoided, and the threads of the drill rod are protected.
