Embodiment

To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this The embodiment of utility model is described in detail.

Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new Type can also be different from other manner described here using other to be implemented, and those skilled in the art can be without prejudice to this reality With doing similar popularization in the case of new intension, therefore the utility model is not limited by following public specific embodiment.

Secondly, the utility model combination schematic diagram is described in detail, when the utility model embodiment is described in detail, for ease of Illustrate, represent that the profile of apparatus structure can disobey general proportion and make partial enlargement, and the schematic diagram is example, its This should not limit the scope of the utility model protection.In addition, the three-dimensional space of length, width and depth should be included in actual fabrication Between size.

As Figure 1-Figure 5, the present embodiment provides a kind of bushing drill drift instrument, for the bushing in lining pipe to be unloaded, The bushing drill drift instrument includes guide cylinder 1, and one end of the guide cylinder 1 is openend 11, the other end edge of the guide cylinder 1 The guide cylinder 1 axially opens up and the screwed hole of its internal run-through 12；The bushing drill drift instrument also includes leading screw 2, the silk Thick stick 2 is spirally connected by the screwed hole 12 and the guide cylinder 1, and the both ends of the leading screw 2 are located at outside the guide cylinder 1 respectively； The bushing drill drift instrument also includes bushing cushion block 3, and the bushing cushion block 3 is spirally connected with the leading screw 2；The bushing drill drift instrument Also include spanner 4, the spanner 4 is connected to drive leading screw 2 to rotate with the leading screw 2 close to one end of the screwed hole 12.

Preferably, the openend 11 of the guide cylinder 1 abuts with one end mouth of pipe of the lining pipe N, or the guide cylinder 1 Openend 11 be set in the lining pipe N one end mouth of pipe it is outer and fixed with lining pipe N, the leading screw 2 passes through the bushing M And stretched out from the other end of the lining pipe N, the bushing cushion block 3 is screwed onto the portion that the leading screw 2 is stretched out outside the lining pipe N On point.

In the present embodiment, shown in reference picture 3, the guide cylinder 1 of bushing drill drift instrument is positioned over bushing M side, described to lead Fixed to the openend 11 of cylinder 1 and the lining pipe N of chassis frame front suspension side, reference picture 2, leading screw 2 passes through guide cylinder 1 The screwed hole 12 that the other end opens up passes through bushing M, reference picture 1, the bushing cushion block 3 the leading screw 2 the other end along leading screw 2 It is threaded into place, reference picture 4, is rotated by the spanner 4 and drive leading screw 2 to rotate, makes the stress of bushing cushion block 3 and along leading screw 2 It is moved axially inward, the bushing cushion block 3 ejects the bushing M in moving process from the lining pipe N, bushing cushion block 3, which move into place rear drill drift process, completes, and the lining pipe N of chassis frame front suspension is separated with bushing M, wait is pressed next time.

Preferably, the internal diameter of the guide cylinder 1 is more than or equal to the internal diameter of the lining pipe N, when in the guide cylinder 1 When footpath is equal to the external diameter of the lining pipe N, the guide cylinder 1 props up the lining pipe N in the bushing drill drift instrument drill drift One end so that the bushing cushion block 3 supports the bushing M, bushing M is released from the lining pipe N, when the guide cylinder When 1 internal diameter is more than the external diameter of the lining pipe N, the openend 11 of the guide cylinder 1 can be set in the one of the lining pipe N End pipe mouth is outer and fixed, so that the bushing cushion block 3 supports the bushing M, bushing M is released from the lining pipe N.

Preferably, the interior hole length of the guide cylinder 1 is more than the length of the bushing M, by such structure, makes described Bushing M can make bushing drill drift process more after being exited from the lining pipe N completely into the endoporus of the guide cylinder 1 It is perfect, if the interior hole length of the guide cylinder 1 is less than the length of the bushing M, it can cause bushing M can not be completely from the lining Exited in sleeve pipe N, cause to increase using difficulty.

Preferably, shown in reference picture 1 and Fig. 4, pushing and pressing part 31 is set on one end end face of the bushing cushion block 3, it is described to push away Support 31 abuts along drill drift direction with one end of the bushing M.

Specifically, the pushing and pressing part 31 is the annular convex edge set on one end end face of the bushing cushion block 3, pass through this The structure of sample, the one end of one end end face of bushing cushion block 3 preferably with the bushing M is abutted, and reduce and make bushing pad The material of block 3, reduces cost.

Preferably, the pushing and pressing part 31 is the multistage of the circumferential array set on one end end face of the bushing cushion block 3 Convex edge, the one end of one end end face of bushing cushion block 3 preferably with the bushing M is abutted, and reduce and make bushing cushion block 3 Material, reduce cost.

Drill drift bushing instrument provided by the utility model, without hydraulic test, pneumatic compression devices, only manually Bushing M in lining pipe N can be removed, it is easy to use, quick, stably, reliability it is high, can be very good to dismantle chassis frame Etc. the bushing M in frock, and with the advantages of being easy to carry.

Above example is only exemplary embodiment of the present utility model, is not used in limitation the utility model, and this practicality is new The protection domain of type is defined by the claims.Those skilled in the art can be in essence of the present utility model and protection domain It is interior, various modifications or equivalent substitution are made to the utility model, this modification or equivalent substitution also should be regarded as new in this practicality In the protection domain of type.
