Description

Technical Field

[0001] The utility model relates to the technical field of shaft boring machines, in particular to a connection structure between a support arm and a fixing seat of a caisson type shaft boring machine. Background Art

[0002] With the increasing demand for underground engineering, vertical shafts are being used in a wider range of applications. Currently, many vertical shafts are constructed using the conventional sinking method, which is slow to excavate, has a low degree of mechanization, poses a high safety risk to construction workers, and is costly.

[0003] A shaft boring machine (TBM) is a type of engineering machinery used for rapid tunnel excavation, enabling intelligent, unmanned underground construction. Existing shaft boring machines have multiple sets of support arms, which, through contact with the pipe wall, ensure that the milling head of the shaft boring machine can excavate the ground below. During the actual excavation process, the relative position of the support arms is easily shifted by the reverse thrust of the milling head, causing a decrease in the verticality accuracy of the excavation. Frequent calibration through monitoring, testing, and auxiliary mechanisms is required, making construction difficult. Furthermore, any deviation in verticality can cause the excavation operation to tilt or even damage the milling head, posing serious quality issues and safety risks to the entire construction process. Summary of the Invention

[0004] The purpose of the utility model is to provide a connection structure between the support arm and the fixed seat of a caisson-type shaft boring machine in response to the above-mentioned deficiencies of the prior art. By setting a support mechanism, a fixed seat and a hydraulic telescopic rod, the support arm of the caisson-type shaft boring machine is positioned in the vertical direction.

[0005] The purpose of this utility model is achieved by the following technical solutions:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] The fixing seat is a steel structure, and an electromagnet plate is provided on the inner side of the two vertical plates of the U-shaped plate.

[0008] The height of the placement groove of the vertical plate is greater than the height of the horizontal plate of the U-shaped plate.

[0009] The supporting mechanism is driven by a lifting device, and the lifting device drives the supporting mechanism to perform lifting motion along the height direction of the fixing seat.

[0010] The fixing seat also includes a bottom plate, which is connected to the bottoms of the two vertical plates and is reinforced by reinforcing ribs.

[0014] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0015] like Figures 1 and 2 As shown, the marks in the figure represent:

[0016] Support arm 1, support mechanism 2, U-shaped plate placement cavity 21, fixing seat 3, bottom plate 31, side plate 32, vertical plate 33, placement groove 331, clamping groove 332, reinforcing rib 34, hydraulic telescopic rod 4, U-shaped plate 5, horizontal plate 51, vertical plate 52, and electromagnet plate 53.

[0017] Example: Figures 1 and 2As shown, this embodiment relates to a connection structure between a support arm and a fixed seat of a caisson-type shaft boring machine, which mainly includes a support mechanism 2, a fixed seat 3, a hydraulic telescopic rod 4 and a U-shaped plate 5. The support mechanism 2 is arranged on the support arm 1 of the caisson-type shaft boring machine, and a U-shaped plate placement cavity 21 is opened on the support mechanism 2. The U-shaped plate placement cavity 21 is used to place the U-shaped plate 5, and both ends of the U-shaped plate 5 extend outside the U-shaped plate placement cavity 21. The fixed seat 3 is a steel structure, and the fixed seat 3 is installed on the inner wall of the shaft. The hydraulic telescopic rod 4 is horizontally arranged, and the fixed end of the hydraulic telescopic rod 4 is installed on the support arm 1, and the telescopic end enters the U-shaped plate placement cavity 21 of the support mechanism 2 and is connected to the U-shaped plate 5. The hydraulic telescopic rod 4 can drive the U-shaped plate 5 to move in the horizontal direction.

[0018] like Figures 1 and 2 As shown, the fixed base 3 includes a bottom plate 31, a side plate 32, and two vertical plates 33. There are two vertical plates 33, and the two vertical plates 33 are arranged opposite each other on the side plates 32. The bottom plate 31 is connected to the bottom of the two vertical plates 33. The vertical plates 33 are provided with a plurality of placement slots 331 along their height direction, and the placement slots 331 are connected to the top of the slots 332. The space formed between the bottom plate 31, the side plates 32, and the vertical plates 33 is used to place the support mechanism 2. The size and shape of this space correspond to the size and shape of the support mechanism 2. The support mechanism 2 is driven by a lifting device, which drives the support mechanism 2 to move up and down along the height direction of the fixed base 3. The bottom plate 33 can be supported by the support mechanism 2 and is reinforced by reinforcing ribs 34. The U-shaped plate 5 consists of a horizontal plate 51 and two vertical plates 52. The two vertical plates 52 are respectively connected to the two ends of the horizontal plate 51. The distance between the outer sides of the two vertical plates 33 of the fixing seat 3 corresponds to the distance between the inner sides of the two vertical plates 52 of the U-shaped plate 2, that is, the inner sides of the vertical plates 52 can contact the outer sides of the vertical plates 33, playing a certain guiding role, and an electromagnet plate 53 is provided on the inner side of the two vertical plates 52 of the U-shaped plate 5. When the position of the support mechanism 2 is determined on the fixing seat 3, the electromagnet plate 53 can be energized to strengthen the connection between the support mechanism 2 and the support mechanism 2. The height of the placement groove 331 of the vertical plate 33 is greater than the height of the cross plate 51 of the U-shaped plate 5, so that the hydraulic telescopic rod 4 can drive the cross plate 51 of the U-shaped plate 5 to enter the placement groove 331 of the vertical plate 33, and when the cross plate 51 of the U-shaped plate 5 contacts the bottom of the placement groove 331 of the vertical plate 33, the lifting device can drive the cross plate 51 of the U-shaped plate 5 to rise, so that the cross plate 51 of the U-shaped plate 5 is clamped in the clamping groove 332 of the vertical plate 33 (the width of the clamping groove 332 of the vertical plate 33 corresponds to the width of the cross plate 51 of the U-shaped plate 5). The size and shape of the cross plate 51 of the U-shaped plate 5 correspond to the size and shape of the clamping groove 332 of the vertical plate 33, respectively, which can prevent the caisson-type shaft boring machine from moving upward during operation.

[0019] In this embodiment, the lifting device drives the support mechanism 2 to move downward along the height direction of the fixed seat 3. When the position of the U-shaped plate 5 corresponds to the position of the placement groove 331 of the fixed seat 3, the hydraulic telescopic rod 4 drives the U-shaped plate 5 to move into the placement groove 331 of the fixed seat 3, and when the horizontal plate 51 of the U-shaped plate 5 contacts the bottom of the placement groove 331 of the fixed seat 3, the hydraulic telescopic rod 4 stops working, and the lifting device drives the support mechanism 2 to rise, so that the horizontal plate 51 of the U-shaped plate 5 is clamped in the clamping groove 332 of the vertical plate 33, and finally the electromagnet plate 53 is energized to realize the positioning and fixation of the support mechanism 2.

[0020] The beneficial technical effect of this embodiment is that the support arm of the caisson-type shaft boring machine is positioned in the vertical direction by providing the support mechanism, the fixing seat and the hydraulic telescopic rod.

[0021] Although the above embodiments have described the concepts and embodiments of the present invention in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, so they are not described here one by one.
