The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] According to the mobile unit body of the embodiment of the present invention, Figures 1 to 14 As shown, the mobile unit body includes a bearing roller group, a support beam and a return roller group, the bearing roller group includes a roller frame and a bearing roller, the support beam is arranged on both sides of the bottom of the roller frame of the bearing roller group, the support beam has a first end and a second end, the first end is provided with a pin hook, the second end is provided with a fixing piece, the pin hook is fixed with the fixing piece of the adjacent mobile unit body, and the return roller group is arranged at the bottom of the roller frame. The pin hook and the fixing piece can cooperate to realize the rapid installation and rapid disassembly of the mobile unit body, and the conveyor body can quickly increase the supplementary feed without stopping the machine and does not affect the excavation speed of the tunnel boring machine.

[0030] The mobile unit body according to the embodiment of the present invention has the advantage of fast assembly and disassembly speed.

[0031] In some embodiments, Figure 3 to Figure 4 As shown, the support beam includes an I-beam, a U-shaped groove is set on the web of the second end of the I-beam, a pin hook is located at the first end of the I-beam, a first hole is set on the upper wing plate and the lower wing plate at the second end of the I-beam, a fixing piece penetrates the first hole and extends to the U-shaped groove, two fixing pieces are arranged relative to each other with respect to the U-shaped groove, and a pin hook is set on the second end of the I-beam.

[0032] Specifically, a portion of the upper and lower wing plates at the first end of the I-beam is cut off to expose the web in the middle and the sharp corners of the web are processed into arcs. The arc can make the two mobile unit bodies rotate a certain angle with the pin as the axis to meet the undulating working conditions of the transportation lane. A U-shaped groove is opened in the middle of the web at the second end of the I-beam, and two groups of first holes are drilled symmetrically on the upper and lower wing plates with the web as the center. The fixing parts correspond to the first holes one by one, and the fixing parts enter from the first holes of the upper wing plate and the lower wing plate respectively. The two fixing parts can relatively close the U-shaped groove and fix the pin hook inside the U-shaped groove.

[0033] In some embodiments, Figure 3 As shown, the fixing member includes a sleeve, a columnar tongue plate and an end plate, the first end of the sleeve passes through the first hole and extends to the U-shaped groove, the second end of the sleeve is parallel to the surface of the upper wing plate or the lower wing plate, the end plate is located at the first end of the sleeve, the columnar tongue plate is inside the sleeve and is slidably connected to the sleeve, the first end of the columnar tongue plate is connected to the end plate through an elastic member, and the second end of the columnar tongue plate extends out of the sleeve and is located in the U-shaped groove.

[0034] Specifically, the sleeve is a circular tube structure, and the sleeve is respectively inserted into the first holes of the upper wing plate and the lower wing plate, one end of the sleeve extends to the first hole of the upper wing plate and the lower wing plate, and the other end of the sleeve is flush and coplanar with the surface of the upper wing plate or the lower wing plate. The sleeve can be welded and fixed, and the elastic member can be a spring, which connects the columnar tongue plate to the end plate, and the columnar tongue plate can slide in the sleeve, and the columnar tongue plates of the sleeves of the upper wing plate and the lower wing plate are arranged relatively to each other, and the second ends of the two columnar tongue plates can be partially abutted, and the second ends of the two columnar tongue plates complete the blocking of the U-shaped groove. When the pin shaft hook needs to be taken out, the columnar tongue plate is pushed to move toward the direction of the end plate, the elastic potential energy of the spring contracts, the distance between the two opposite columnar tongue plates becomes larger, and the pin shaft hook falls off. After the columnar tongue plate is released, the columnar tongue plate automatically resets and blocks the U-shaped groove under the push of the spring.

[0035] In some embodiments, Figure 5 As shown, the sleeve is provided with reinforcing ribs.

[0036] Specifically, the reinforcing ribs are arranged on the outer side of the sleeve, and the reinforcing ribs connect the sleeve with the end of the U-shaped groove to improve the stability of the sleeve. The reinforcing ribs correspond to the sleeve one by one.

[0037] In some embodiments, Figure 7 As shown, the first end of the columnar tongue plate is cylindrical, the second end of the columnar tongue plate is a tongue-shaped plate, the side of the tongue-shaped plate facing the U-shaped groove is a straight surface, and the side of the tongue-shaped plate away from the U-shaped groove is a curved surface.

[0038] Specifically, the first end of the columnar tongue plate is cylindrical, and the first end of the cylinder slides in the sleeve and is connected to the end plate through a spring. The second end of the columnar tongue plate is a tongue-shaped plate. The tongue-shaped plates of the sleeves of the upper wing plate and the lower wing plate are relatively arranged. The pin hook first contacts the curved surface of the tongue plate, and the radial force decomposed at the contact point pushes the columnar tongue plate toward the end plate. The spring is squeezed and contracted, and the gap between the tongue plates becomes larger and the pin hook passes through. The pin hook enters the bottom of the U-shaped groove, and the tongue plate is reset and blocked by the spring. At this time, the contact side of the pin hook and the tongue plate is a flat surface, and there is no force pushing toward the end plate at the contact point, and the columnar tongue plate cannot be pushed to move, forming a self-locking.

[0039] In some embodiments, Figures 3 to 6 , Fig.13 and Fig.14 As shown, the pin hook includes a first pin and a second pin, the first pin and the second pin are fixedly connected via a connecting plate, the first pin is connected to the second end of the I-beam, and the distance between the second pin and the second end of the I-beam is greater than or equal to the distance that the second pin penetrates into the fixing part of the adjacent mobile unit body.

[0040] Specifically, the pin hook is a chain plate type pin hook, and the first pin and the second pin form a chain type closed loop structure through a connecting plate. A notch is processed in the middle of the first pin, and the end of the web of the second end of the I-beam is inserted into the notch and fixed. The distance between the second pin and the end of the web of the second end of the I-beam is enough to insert the fixing part of the adjacent mobile unit body to ensure the fixing effect.

[0041] In some embodiments, Figure 8 As shown, a bearing roller installation area is provided in the center of the roller frame, and a mounting hole is provided on the bottom plate of the roller frame.

[0042] Specifically, the roller frame can be a keel type roller frame. The keel type roller frame is a frame structure composed of rods, which is light in weight and easy to carry. Mounting holes are set on the bottom plate of the roller frame to fix the roller frame. Stop rollers are set on the upper ends of the load-bearing rollers on both sides to prevent the belt from running away. The stop rollers have large stop plates, which can prevent the belt from running away laterally and prevent the belt from moving upward.

[0043] In some embodiments, Figure 1 As shown in FIG2 , the mobile unit body further includes a walking mechanism, which includes a walking wheel and a slot structure. The slot structure has a pin hole for fixing the support beam, and the moving direction of the walking wheel is the same as the extending direction of the slot structure.

[0044] Specifically, the slot structure is connected to the running wheels through the legs, and the crossbeam connects the two legs to prevent the two supporting beams from moving during the movement of the fuselage. The slot structure is used to support the I-beam, and the pin hole is used to fix the supporting beam and the slot structure. The moving direction of the running wheels is fixed, and the running wheels move along the extension direction of the slot of the slot structure to prevent the fuselage from shifting.

[0045] In some embodiments, Fig. 9 As shown, the return roller set includes a lifting lug and a return roller.

[0046] Specifically, the lifting lug is a plate structure, and a notch is arranged on the side of the lifting lug to install the return roller.

[0047] In some embodiments, Fig.10 and Fig.11 As shown, the fixing pin passes through the mounting hole and the pin hole to fix the roller frame to the supporting beam and the walking mechanism, and the fixing pin has two teeth, and an angle is formed between the two teeth.

[0048] Specifically, the fixing pin passes through the mounting hole of the roller frame to fix the return roller group to the roller frame, and the fixing pin passes through the pin hole of the support beam and the pin hole of the slot structure of the walking mechanism to fix the support beam to the walking mechanism. The fixing pin is used to achieve a quick connection between various components. The fixing pin can be bent from round steel, with a positioning pin in the middle and teeth at both ends. Inserting into two jacks on the same center line of the walking mechanism forms an elastic self-locking function, which can prevent the fixing pin from falling off.
