Description

Technical Field

[0001] The utility model belongs to the technical field of side wall trolleys, and in particular relates to a self-tracking walking device for a side wall hydraulic trolley. Background Art

[0002] Hydraulic sidewall trolleys are primarily used in subway sidewall construction. Prior art discloses hydraulic trolleys, such as Patent Publication No. CN220748289U, which discloses a step-by-step hydraulic trolley for tunnel partition walls. The trolley comprises a formwork, a gantry located on the side of the formwork away from the tunnel partition wall, a hydraulic system mounted on the gantry, and a power distribution device mounted on the gantry. The hydraulic trolley disclosed in this patent utilizes a step-by-step movement mechanism, allowing for direct lateral adjustment of the trolley into position via a translation mechanism at its base. Compared to traditional solutions, this significantly reduces the labor and time required for adjustment, improving construction efficiency.

[0003] It is undeniable that the step-by-step hydraulic trolley disclosed in this patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: when moving the trolley forward or backward, it is mainly achieved by extending and retracting the third hydraulic cylinder relatively set on the bottom beam of the portal frame. However, in this way of moving with the help of a hydraulic cylinder, the distance the trolley moves each time will be limited by the length of the extension of the telescopic end of the hydraulic cylinder. If the distance the trolley needs to move is greater than the length of the extension of the hydraulic cylinder, it is necessary to repeatedly control the extension and retraction of the relatively set third hydraulic cylinder to move the walking support. When moving the walking support, it is necessary to first lift the walking support off the ground. In this process, it is necessary to control the second hydraulic cylinder to make the base leave the ground and fall back to the ground, which is cumbersome to operate.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0034] Example

[0035] See attached Figure 1-7 , a side wall hydraulic trolley self-tracking walking device, comprising:

[0036] Template 100;

[0037] A door frame 200 is provided on the side of the template 100 away from the side wall, and the door frame 200 includes two parallel and spaced bottom beams 201;

[0038] Two longitudinal sliding rails 300 are arranged in parallel and spaced apart below the door frame 200 and extend along the length direction of the door frame 200;

[0039] The longitudinal movement mechanism 400 is arranged on the top of the longitudinal movement slide 300, and the longitudinal movement mechanism 400 includes two longitudinal movement slides 401 arranged at intervals on the top of the longitudinal movement slide 300 and matched with the longitudinal movement slide 300 and fixedly connected to the door frame 200 at the top, a positioning slide 402 arranged on the top of the longitudinal movement slide 300 and matched with the longitudinal movement slide 300 for sliding guidance and located between the two longitudinal movement slides 401, and a longitudinal movement oil cylinder 403 with one end hinged to the positioning slide 402 and the other end hinged to one of the longitudinal movement slides 401; wherein the longitudinal movement slide 401 includes a longitudinal movement connecting seat 4011 fixedly connected to the bottom of the door frame 200 at the top, and a longitudinal movement connecting seat 401 installed on the longitudinal movement connecting seat 402. 011 and extend from the bottom of the longitudinal connecting seat 4011 and roll along the longitudinal sliding rail 300, and the limiting wheels 4013 installed on both sides of the longitudinal connecting seat 4011; wherein, the limiting wheels 4013 are composed of an upper wheel body 40131 and a lower wheel body 40132 formed in one piece, the upper wheel body 40131 is located on the outside of the top flange plate (not marked in the drawings) of the longitudinal sliding rail 300, the diameter of the lower wheel body 40132 is larger than the diameter of the upper wheel body 40131, and the lower wheel body 40132 is located at the bottom of the top flange plate of the longitudinal sliding rail 300; referring to the drawings, it can be clearly seen that a flange plate is formed in one piece on both sides of the top of the longitudinal sliding rail 300;

[0040] A plurality of transverse mechanisms 500 are symmetrically arranged on both sides of the bottom of the door frame 200, and the transverse mechanism 500 includes a transverse slide rail 501 which is horizontally arranged and perpendicular to the longitudinal slide rail 300 and has a support foot 5011 fixed at both ends of the bottom, a transverse slide 502 which is arranged on the top of the transverse slide rail 501 and cooperates with the sliding guide of the transverse slide rail 501, a guide slide 503 which is fixed on the top of the transverse slide 502 and vertically passes through the bottom beam 201 and cooperates with the sliding guide of the bottom beam 201, and a bottom fixedly connected to the guide slide 503 and vertically upwardly hinged to the top of the door frame 200. The lifting cylinder 504 of the frame 200 and the cylinder body are hinged to one end of the transverse slide 501 and the telescopic end is hinged to the transverse cylinder 505 of the transverse slide 502; wherein, the transverse slide 501 is symmetrically fixed with a transverse limit plate 5012 in the shape of the number "7" on both sides, the vertical section of the transverse limit plate 5012 is located on the outside of the bottom flange plate of the transverse slide 502, and the horizontal section of the top of the vertical section of the transverse limit plate 5012 is located on the top of the bottom flange plate of the transverse slide 502; referring to the accompanying drawings, it can be seen that a flange plate is integrally formed on both sides of the bottom of the transverse slide 502;

[0041] In this embodiment, the specific structure of the positioning slide 402 is as follows: the positioning slide 402 includes a positioning slide 4021 that slides with the longitudinal slide rail 300, a positioning limit plate 4022 symmetrically fixed on both sides of the positioning slide 4021, a mounting seat 4023 fixed to the middle position of the top of the positioning slide 4021, a tongue 4024 located in the mounting seat 4023, and a mounting pin 4025 that vertically passes through the mounting seat 4023 and the tongue 4024; wherein, the mounting seat 402 3 is respectively provided with a mounting hole 40231 at both ends, and a limit pin 4026 is inserted into the mounting hole 40231; a plurality of limit slots 301 corresponding to the tongues 4024 are evenly provided on the top of the longitudinal slide rail 300; the positioning limit plate 4022 is in the shape of the letter "L", and the vertical section of the positioning limit plate 4022 is located on the outer side of the top flange plate of the longitudinal slide rail 300, and the horizontal section at the bottom of the vertical section of the positioning limit plate 4022 is located at the bottom of the top flange plate of the longitudinal slide rail 300.

[0042] It should be noted that, in this embodiment, the longitudinal oil cylinder 403 , the lifting oil cylinder 504 and the transverse oil cylinder 505 are all connected to an external hydraulic system. The longitudinal slide rail 300 is located between the two supporting legs 5011 of the transverse slide rail 501 .

[0043] When the gantry 200 moves forward longitudinally, the external hydraulic system returns oil to the lifting cylinder 504 to reduce pressure, causing the telescopic end of the lifting cylinder 504 to retract, and the bottom beam 201 of the gantry 200 to slide downward relative to the guide slide 503. During this process, the longitudinal slide rail 300 falls to the ground and provides support for the longitudinal mechanism 400 and the gantry 200. When the telescopic end of the lifting cylinder 504 continues to retract, the guide slide 503 slides upward relative to the bottom beam 201 of the gantry 200, driving the transverse slide 502 upward. As the transverse slide 502 moves upward, its flange plates on both sides abut against the bottom of the transverse limit plate 5012. In this way, the transverse slide 502 drives the transverse slide rail 501 and the support leg 5011 to move upward synchronously, thereby lifting the support leg 5011 off the ground and stopping the return oil pressure reduction to the lifting cylinder 504. Then the staff will completely remove the limit pin 4026 from the mounting hole 40231, and use the external rod to press the top of the tongue 4024 to make the bottom of the tongue 4024 separate from the longitudinal slide rail 300, and use the external oil pressure system to press the longitudinal cylinder 403, and the longitudinal cylinder 403 will push the positioning slide 402 to slide backward along the longitudinal slide rail 300. When the positioning slide 402 slides to the position of the limit slot 301 of the longitudinal slide rail 300, the bottom of the tongue 4024 falls into the limit slot 301, and a limit pin 4026 is installed in the mounting hole 4026 on the rear side of the top of the tongue. The top of the pick tongue 4024 is located in the mounting hole 40231 in front of the limiting pin 4026. When the positioning slide 402 continues to slide backward, the bottom of the pick tongue 4024 abuts against the inner wall of the limiting slot 301 and cannot escape from the limiting slot 301. The top of the pick tongue 4024 abuts against the front side of the limiting pin 4026. In this way, the limiting slot 301 and the limiting pin 4026 limit the pick tongue 4024 so that it cannot rotate around the mounting pin 4025 as the rotation axis, thereby achieving the positioning of the positioning slide 402. At this time, the positioning slide 402 cannot move. The telescopic end of the longitudinal movement cylinder 403 continues to extend, and the longitudinal movement cylinder 403 generates a forward thrust on the longitudinal movement slide 401, which drives the gantry 200 forward.

[0044] After the telescopic end of the longitudinal moving cylinder 403 is fully extended, the external oil pressure system returns oil to the longitudinal moving cylinder 403 to reduce the pressure, and the telescopic end of the longitudinal moving cylinder 403 retracts, driving the positioning slide 402 to move forward along the longitudinal moving slide rail 300. The staff uses an external rod to press the top of the tongue 4024 to make the bottom of the tongue 4024 disengage from the limit slot 301. When the positioning slide 402 moves forward to the position of the next limit slot 301, the tongue 4024 is released, and the bottom of the tongue 4024 falls into the limit slot 301. At this time, the top of the tongue 4024 is located in front of the limit pin 4026; then the external oil pressure system pressurizes the longitudinal cylinder 403, and the telescopic end of the longitudinal cylinder 403 extends, and the longitudinal cylinder 403 pushes the positioning slide 402 to slide backward along the longitudinal slide rail 300. The bottom of the tongue 4024 abuts against the inner wall of the limit slot 301 and cannot escape from the limit slot 301. The top of the tongue 4024 abuts against the front side of the limit pin 4026, and the positioning of the positioning slide 402 is realized again. At this time, the positioning slide 402 cannot move. The telescopic end of the longitudinal movement oil cylinder 403 continues to extend, and the longitudinal movement oil cylinder 403 produces a forward thrust to the longitudinal movement slide 401, and the longitudinal movement slide 401 drives the door frame 200 to move forward. Such a cycle can make the door frame 200 move forward continuously.

[0045] When the door frame 200 moves longitudinally backward, the staff will take out all the limit pins 4026 from the mounting holes 40231, and use the external rod to press the top of the tongue 4024 to make the bottom of the tongue 4024 separate from the longitudinal slide rail 300. The external oil pressure system pressurizes the longitudinal cylinder 403, and the longitudinal cylinder 403 pushes the positioning slide 402 to slide backward along the longitudinal slide rail 300. When the positioning slide 402 slides to the position of the limit slot 301 of the longitudinal slide rail 300, the tongue 4024 is released, and the bottom of the tongue 4024 falls into the limit slot 301. A limit pin 4026 is installed in the mounting hole 40231 on the front side of the top of the tongue, and the tongue 40 The top of the pick tongue 4024 is located behind the limit pin 4026; then the external oil pressure system returns oil to the longitudinal cylinder 403 and reduces the pressure, and the telescopic end of the longitudinal cylinder 403 retracts, driving the positioning slide 402 to move forward along the longitudinal slide rail 300. At this time, the bottom of the pick tongue 4024 abuts against the inner wall of the limit slot 301 and cannot escape from the limit slot 301. The top of the pick tongue 4024 abuts against the rear side of the limit pin 4026. In this way, the limit slot 301 and the limit pin 4026 limit the pick tongue 4024 so that it cannot rotate about the mounting pin 4025 as the rotation axis, thereby achieving the positioning of the positioning slide 402. At this time, the positioning slide 402 cannot move. The telescopic end of the longitudinal cylinder 403 continues to retract, and the longitudinal cylinder 403 generates a backward thrust on the longitudinal slide 401, which drives the gantry 200 to move backward. Referring to the principle of continuous forward longitudinal movement of the gantry 200, which will not be elaborated here, the continuous backward longitudinal movement of the gantry 200 can be achieved.

[0046] When the support leg 5011 leaves the ground, the external hydraulic system pressurizes the transverse cylinder 505, the telescopic end of the transverse cylinder 505 extends, and the transverse cylinder 505 generates thrust on the transverse slide rail 501, thereby causing the transverse slide rail 501 to move laterally relative to the transverse slide seat 502.

[0047] When the gantry 200 moves horizontally to the left or right, the external oil pressure system pressurizes the lifting cylinder 504, the telescopic end of the lifting cylinder 504 extends, and the guide slide 503 moves downward relative to the bottom beam 201 of the gantry 200, and the guide slide 503 drives the transverse slide 502, the transverse slide rail 501 and the support foot 5011 to move downward, and the support foot 5011 is supported on the ground; the external oil pressure system continues to pressurize the lifting cylinder 504, the bottom beam 201 slides upward relative to the guide slide 503, and the gantry 200 drives the entire longitudinal mechanism 400 to move upward. When the longitudinal connecting seat 4011 moves upward, the bottom of the lower wheel body 40132 abuts against the flange plate at the top of the longitudinal slide rail 300, thereby driving the longitudinal slide rail 300 to move upward, thereby causing the longitudinal slide rail 300 to leave the ground, and stopping pressurizing the lifting cylinder 504. In this embodiment, the transverse oil cylinders 505 are located inside the transverse slide 502, with the telescopic end of the transverse oil cylinder 505 on one side in an extended state and the telescopic end of the transverse oil cylinder 505 on the other side in a retracted state. When the gantry 200 is moved horizontally, the external hydraulic system pressurizes the transverse oil cylinder 505 in the retracted state and returns oil to the transverse oil cylinder 505 in the extended state, thereby driving the transverse slide 502 to slide relative to the transverse slide rail 501. When the transverse slide 502 moves, it also drives the guide slide 503 to move. Since the guide slide 503 passes through the bottom beam 201, the guide slide 503 drives the entire gantry 200 to move horizontally through the bottom beam 201.

[0048] When the longitudinal slide 300 is off the ground, the limit pin 4026 is completely taken out of the mounting hole 40231, and the top of the tongue 4024 is pressed by the external rod to make the bottom of the tongue 4024 separate from the longitudinal slide 300. The longitudinal cylinder 403 is pressurized by the external oil pressure system, and the longitudinal cylinder 403 pushes the positioning slide 402 to slide backward along the longitudinal slide 300. When the positioning slide 402 slides to the position of the limit slot 301 of the longitudinal slide 300, the tongue 4024 is released, and the bottom of the tongue 4024 falls into the limit slot 301. A limit pin 4026 is installed in the mounting hole 40231 on the rear side of the top of the tongue, and the top of the tongue 4024 is located in front of the limit pin shaft 4026; the external oil pressure system continues to pressurize the longitudinal slide When the oil cylinder 403 is pressurized, the bottom of the tongue 4024 abuts against the inner wall of the limit slot 301 and cannot escape from the limit slot 301. The top of the tongue 4024 abuts against the front side of the limit pin 4026. In this way, the limit slot 301 and the limit pin 4026 limit the tongue 4024 so that it cannot rotate with the mounting pin 4025 as the axis, thereby realizing the positioning of the positioning slide 402. At this time, the positioning slide 402 cannot move; when the telescopic end of the longitudinal cylinder 403 continues to extend, the longitudinal cylinder 403 generates a backward thrust on the positioning slide 402, and the positioning slide 402 drives the longitudinal slide rail 300 to move backward. By adjusting the position of the positioning slide 402 in different limit slots 301, the continuous backward movement of the longitudinal slide rail 300 can be achieved.

[0049] Similarly, remove all the limit pins 4026 from the mounting hole 40231, and use the external rod to press the top of the tongue 4024 so that the bottom of the tongue 4024 is separated from the longitudinal slide rail 300. The external oil pressure system reduces the return oil pressure of the longitudinal cylinder 403, and the longitudinal cylinder 403 pulls the positioning slide 402 to slide forward along the longitudinal slide rail 300. When the positioning slide 402 slides to the position of the limit slot 301 of the longitudinal slide rail 300, release the tongue 4024, and the bottom of the tongue 4024 falls into the limit slot 301. Install a limit pin 4026 in the mounting hole on the front side of the top of the tongue. In the mounting hole 40231, the top of the tongue 4024 is located on the rear side of the limit pin shaft 4026; then the external oil pressure system continues to return oil and reduce the pressure of the longitudinal movement cylinder 403, and the bottom of the tongue 4024 abuts against the inner wall of the limit slot 301 and cannot escape from the limit slot 301. The top of the tongue 4024 abuts against the rear side of the limit pin 4026. In this way, the limit slot 301 and the limit pin 4026 limit the tongue 4024 so that it cannot rotate with the mounting pin 4025 as the axis of rotation, thereby realizing the positioning of the positioning slide 402, and the positioning slide 402 cannot move at this time. The telescopic end of the longitudinal movement cylinder 403 continues to retract, and the longitudinal movement cylinder 403 generates a forward pulling force on the positioning slide 402, and the positioning slide 402 drives the longitudinal movement slide 300 to move forward. By adjusting the position of the positioning slide 402 in different limit slots 301, the continuous forward movement of the longitudinal movement slide 300 can be achieved.
