Description

Technical Field

[0001] The utility model relates to the technical field of pin shaft disassembly equipment, in particular to a pin shaft strong disassembly device. Background Art

[0002] At present, when dismantling a tunnel boring machine underground, due to the long service time of the tunnel boring machine in the humid environment underground, some pins are not properly lubricated and maintained on a daily basis, and it is often difficult to remove the pins. If one pin cannot be removed, the overall dismantling work will be delayed. At the same time, the dismantling cannot be maintained smoothly during the dismantling, causing irreversible damage or deformation to the pins. Once the dismantling is completed, the pins need to be replaced or repaired, which increases additional maintenance costs and workload. Utility Model Content

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figure 1-3 The utility model provides an embodiment: a pin shaft strong disassembly device, comprising a traveling vehicle 1, a lifting device 3 installed on the traveling vehicle 1, a disassembly device 5 installed on the lifting device 3 and a hand pressure pump 6,

[0020] The removal device 5 includes a screw connecting rod 501, a pulling device 502, a pin sleeve 503, a hammer 504, an impact plate 505, and a hand pull plate 506. The top of the screw connecting rod 501 is fixedly connected to the impact plate 505. The screw connecting rod 501 is used to transmit tension. When the hand pump 6 applies pressure, the screw connecting rod 501 will be stretched and the force applied to it will be transmitted to the pin sleeve 503, thereby applying tension to remove the pin. The other end is provided with a pin sleeve 503, and the other end of the pin sleeve 503 is provided with a pulling device 502. The pulling device 502 applies continuous tension and includes a hydraulic system to provide continuous tension through the hand pump 6. When tension is applied to the screw connecting rod 501, it will be transmitted to the pin sleeve 503 to help remove the pin. A swing hammer 504 is arranged between the puller 502 and the impact plate 505. The swing hammer 504 slides with the screw connecting rod 501. When the hand pump 6 applies continuous tension and fails to successfully remove the pin, the swing hammer rod 504 is pulled by the hand pull plate 506 to slide and collide with the impact plate 505, providing additional explosive force to help quickly remove the pin. The hand pump 6 pipeline is connected to the puller 502. The hand pump 6 is used to provide hydraulic pressure. When the operator operates the hand pump 6, it will generate pressure and send hydraulic oil into the hydraulic system, which is transmitted to the puller 502 to apply continuous tension. The walking vehicle 1 includes a push rod 2, a bracket, and a walking wheel. The bottom end of the push rod 2 is connected to a bracket. The bracket is welded by a pair of triangular frames and is located on the front and rear sides of the walking vehicle 1. The bottom end of the bracket is connected to a walking wheel. The walking vehicle 1 provides mobile support so that the device can be moved to the place where it needs to be removed.

[0021] Example 2: Please refer to Figure 3 , based on Example 1, it also has the following structure:

[0022] The lifting device 3 includes a support column 301, a gear 302, a rack 303, and a push rod 304. The support column 301 is installed at the four corners of the top of the traveling vehicle 1, and the gear 302 is arranged in the support column 301. A hand wheel is fixedly connected to the gear 302, and a rack 303 is meshed on one side of the gear 302. A push rod 304 is fixedly connected to the top of the rack 303, and a placement plate 4 is fixedly connected to the top of the push rod 304. The lifting device 3 is used to lift the removal device 5, and lift the removal device 5 to the point where it needs to be removed, so that the device is stably aligned with the pin shaft that needs to be removed, so as to avoid the pin shaft after removal from being broken or deformed due to the instability of the device during removal, thereby reducing the cost of use. The inner diameter of the pin shaft sleeve 503 matches the diameter of the pin shaft, and is used to connect the pin shaft inside. The pin shaft sleeve 503 is used to protect the pin shaft and provide a connection point. Its inner diameter matches the diameter of the pin shaft, and the pin shaft can be connected inside. When pulling force is applied, the pin shaft sleeve 503 can transmit force evenly and protect the pin shaft from damage during the removal process. A number of connecting rods are evenly distributed on the corresponding end faces of the swing hammer 504 and the impact plate 505. The connecting rods penetrate the impact plate 505, and a hand pull plate 506 is provided on the top to operate the swing hammer 504. The hand pull plate 506 is in the same direction as the pressure rod of the hand pump 6. This arrangement allows single-person operation without the need for multiple people to perform the operation.

[0023] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
