Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and more specifically, to a construction operation platform for a traffic tunnel. Background Technology

[0002] Traffic tunnels are common structural features in highways and railways. Currently, when repairing or constructing traffic tunnels, the work is quite difficult when repairing the top of the tunnel because the tunnel is built inside a hill. Therefore, construction operation platforms for traffic tunnels are often used.

[0003] Currently, the following technical problems often occur during the use of construction operation platforms for traffic tunnels on the market:

[0004] Existing construction operation platforms for traffic tunnels cannot increase the stability of the entire platform during construction by raising it, making it easy for construction workers to tip over. In addition, in order to increase the operating space of the entire construction operation platform, extra power is usually required, which brings certain inconvenience to the construction workers, reduces work efficiency and construction safety. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a construction operation platform for traffic tunnels that can increase the stability of the entire construction operation platform during construction by raising it, preventing the platform from tipping over, and simultaneously enabling the extension components to extend outward, thereby increasing the operational space of the entire construction operation platform, bringing convenience to construction personnel, eliminating the need for additional power for the extension components, and improving work efficiency and construction safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A construction operation platform for a traffic tunnel includes a mobile vehicle. The top of the mobile vehicle has a first chute, and a shear-type lifting platform is slidably fitted inside the first chute. Two sets of symmetrical U-shaped frames are fixed on the top of the mobile vehicle. An extension plate is fixed on one side of each set of U-shaped frames. A T-shaped support is hinged to one side of the extension plate. Two symmetrical baffles are fixed on one side of the T-shaped support. An inclined rotating arm is fixedly connected between the two baffles. Sliding rods are fixed on both opposite sides of the inclined rotating arm.

[0008] The top of the shear-type lifting platform is equipped with an operating table, and two sets of symmetrical side plates are fixed to the bottom of the operating table. Each set of side plates has two symmetrical sliding grooves through one side, and the sliding rod slides in conjunction with the sliding groove.

[0009] The top of the control panel has two sets of symmetrical rectangular slots located above each set of side panels.

[0010] Each group of side plates consists of two, arranged symmetrically on the left and right sides, and each group of rectangular slots consists of two, arranged symmetrically on the front and back sides.

[0011] The invention is further configured such that: a drive motor is fixed to the bottom of the mobile vehicle, and a bidirectional threaded screw is fixed to the output shaft of the drive motor, and the bidirectional threaded screw is threadedly connected to the shearing lifting platform.

[0012] The top of the shear-type lifting platform is hinged with two symmetrical sliding seats. A sliding plate is fixed at the center of the top of the two sliding seats, and a sliding hole is opened on one side of the sliding plate.

[0013] The present invention is further configured such that: two symmetrical support plates are fixed at the center of the top of the operating table, and a guide rod is fixed between the two support plates, the guide rod being slidably engaged with a sliding hole.

[0014] The top of the control panel is provided with a second sliding groove, which slides in conjunction with the slide plate.

[0015] The present invention is further configured such that: a rectangular vertical plate is fixed at the top of the inclined rotating arm, and pins are fixed on both opposite sides of the rectangular vertical plate, and a lifting arm is rotatably fitted on the circumferential side of the pins.

[0016] A rotating hole is provided on one side of the lifting arm, and a rotating groove is provided on the top of the lifting arm. The rotating groove is rotatably engaged with a rectangular vertical plate. Pin holes are provided on both inner sidewalls of the rotating groove, and the pin holes are rotatably engaged with pin posts. A lever is rotatably engaged on the inner wall of the rotating hole.

[0017] The present invention is further configured such that: the lever component includes an I-shaped slider, a U-shaped frame is provided on one side of the I-shaped slider, a rotating shaft is fixed on the inner wall of the U-shaped frame, a lever plate is fixed on one outer side of the U-shaped frame, a lever is fixed on one side of the lever plate, and the rotating shaft is rotatably engaged with the rotating hole.

[0018] The top of the operating platform is fixed with several supporting vertical plates, and the top of the supporting vertical plates is fixed with a U-shaped platform plate. The U-shaped platform plate is fixed with limit plates on both opposite sides, and two symmetrical extension pieces slide between the two limit plates.

[0019] The present invention is further configured such that: the extension member includes an extension plate, and the extension plate has limit grooves on both opposite sides, and the limit grooves slide in cooperation with the limit plate.

[0020] The bottom of the expansion plate is fixed with two symmetrical support baffles. Each of the two support baffles has a through-cut oblique groove on one side, and the oblique groove is slidably engaged with the lever.

[0021] The present invention is further configured such that: two sets of symmetrical connecting vertical plates are fixed between the U-shaped platform plate and the operating table, and a guide vertical groove is provided through one side of each set of connecting vertical plates.

[0022] Each group consists of two connecting vertical plates, which are symmetrically distributed on the left and right sides.

[0023] The I-shaped slider slides in conjunction with the guide vertical groove.

[0024] The present invention is further configured such that: a climbing ladder is fixed to one side of a set of connecting vertical plates, and a ladder for ascending is fixed to the bottom of the climbing ladder.

[0025] The invention is further configured such that: a through hole is provided on the top of the mobile vehicle below the U-shaped frame; a hydraulic cylinder is fixed to the top of the U-shaped frame; a chassis is fixed to the telescopic end of the hydraulic cylinder; and several anti-slip balls are fixed to the bottom of the chassis.

[0026] The mobile vehicle is equipped with two symmetrical counterweights on its top.

[0027] The advantages of this invention are:

[0028] 1. This invention achieves the hinged rotation of the T-shaped support by having its bottom in close contact with the construction ground. No additional force is required for the T-shaped support to rotate during the entire process; the hinged rotation is achieved solely through the upward movement of the construction platform. This ensures that the bottom of the T-shaped support is fully in contact with the construction ground, increasing the stability of the entire construction platform during construction, preventing the platform from tipping over, and improving construction safety.

[0029] 2. This invention utilizes the sliding engagement between the inclined groove and the lever to drive the support baffle to slide outward at the top of the operating platform. During the sliding process, the sliding engagement between the limiting groove and the limiting plate allows the extension component to expand outward between the operating platform and the U-shaped platform plate. Thus, by raising the construction operating platform, the extension component extends outward, increasing the operable space of the entire construction operating platform, providing convenience for construction personnel during the construction process, and eliminating the need to provide additional power for the extension component, thereby improving work efficiency.

[0030] 3. This invention increases the contact area between the entire construction platform and the construction site by activating the hydraulic cylinder fixed at the top of the U-shaped frame until the chassis fixed at the extension end of the hydraulic cylinder and several anti-slip balls fixed at the bottom of the chassis come into contact with the construction site. This increases the stability of the entire construction platform during the construction process, prevents the entire construction platform from shaking during the construction work performed by workers on top of the platform, and increases the safety of the construction process.

[0031] 4. The present invention increases the weight on both sides of the entire construction operation platform by setting two counterweights on the top of the mobile vehicle, preventing the platform from tilting left and right during the left and right movement of construction personnel, and increasing the safety of the construction process.

Example 1

[0049] Please see Figure 1-13 The present invention provides the following technical solutions:

[0050] A construction operation platform for a traffic tunnel, specifically comprising a mobile vehicle 1, with a first chute 102 on the top of the mobile vehicle 1, a shear-type lifting platform 103 slidably fitted inside the first chute 102, two symmetrical sets of U-shaped frames 104 fixed on the top of the mobile vehicle 1, an extension plate 105 fixed on one side of each U-shaped frame 104, a T-shaped support seat 106 hinged to one side of the extension plate 105, two symmetrical baffles 107 fixed on one side of the T-shaped support seat 106, and a slanted rotating arm 108 fixedly connected between the two baffles 107. 08. Slide rods 109 are fixed on both sides; the top of the shear-type lifting platform 103 is equipped with an operating platform 2, and two sets of symmetrical side plates 201 are fixed on the bottom of the operating platform 2. Two symmetrical sliding grooves 202 are opened through one side of each set of side plates 201, and the slide rods 109 slide in cooperation with the sliding grooves 202; two sets of symmetrical rectangular grooves 203 are opened above each set of side plates 201 on the top of the operating platform 2; there are two side plates 201 in each set, which are symmetrically arranged on the left and right, and two rectangular grooves 203 in each set, which are symmetrically arranged front and back.

[0051] The specific application of this embodiment is as follows: During the use of the platform, after the construction personnel climb onto the U-shaped platform 207, they can be transported to a designated height by the rising of the shear-type lifting platform 103 for subsequent traffic tunnel construction. During the rising of the shear-type lifting platform 103, the sliding engagement between the sliding rods 109 fixed on both sides of the inclined arm 108 near one end and the sliding grooves 202 penetrating one side of each set of side plates 201 allows the inclined arm 108 to gradually press outward and downward. During the outward and downward pressing process, the T-shaped support base 106 fixed at the bottom of the inclined arm 108... With the hinged engagement with one side of the extension plate 105, it gradually begins to press down until the construction personnel are sent to the designated height. At this point, the bottom of the T-shaped support 106 comes into contact with the construction ground. Throughout the process, no additional force is required to provide hinge rotation for the T-shaped support 106. The hinge rotation of the T-shaped support 106 is achieved simply by utilizing the upward movement of the construction platform. This allows the bottom of the T-shaped support 106 to fully contact and support the construction ground, increasing the stability of the entire construction platform during construction, preventing the platform from tipping over, and improving construction safety. Example 2

[0052] Please see Figure 1-13This second embodiment is an improvement on the first embodiment as follows: Specifically, a drive motor 110 is fixed to the bottom of the mobile vehicle 1, and a bidirectional threaded screw 111 is fixed to the output shaft of the drive motor 110. The bidirectional threaded screw 111 is threadedly connected to the shearing lifting platform 103. Two symmetrical sliding seats 112 are hinged to the top of the shearing lifting platform 103. A sliding plate 113 is fixed at the center of the top of the two sliding seats 112, and a sliding hole 114 is opened on one side of the sliding plate 113. Two symmetrical support plates 204 are fixed at the center of the top of the operating platform 2. A guide rod 205 is fixed between the two support plates 204. The guide rod 205 is connected to the sliding plate 113. Hole 114 slides in fit; a second slide groove 210 is provided on the top of the operating table 2, and the second slide groove 210 slides in fit with the slide plate 113; a rectangular vertical plate 115 is fixed to the top of the inclined rotating arm 108, and pins 116 are fixed on both opposite sides of the rectangular vertical plate 115. A lifting arm 3 is rotatably fitted to the circumference of the pins 303; a rotating hole 301 is provided on one side of the lifting arm 3, and a rotating groove 302 is provided on the top of the lifting arm 3. The rotating groove 302 is rotatably fitted with the rectangular vertical plate 115, and pin holes 303 are provided on both opposite inner walls of the rotating groove 302. The pin holes 303 are rotatably fitted with the pins 116, and the inner wall of the rotating hole 301 is rotatably fitted with... The lever component 4 includes an I-shaped slider 401, a U-shaped frame 402 on one side of the I-shaped slider 401, a rotating shaft 403 fixed to the inner wall of the U-shaped frame 402, a lever plate 404 fixed to one outer side of the U-shaped frame 402, a lever 405 fixed to one side of the lever plate 404, and the rotating shaft 403 rotatably engaging with the rotating hole 301; several supporting vertical plates 206 are fixed to the top of the operating platform 2, a U-shaped platform plate 207 is fixed to the top of the supporting vertical plates 206, and limit plates 208 are fixed to opposite sides of the U-shaped platform plate 207, with two symmetrical extension parts 5 slidingly engaging between the two limit plates 208; the extension parts 5 include extension plates 50 1. Limiting grooves 502 are provided on both opposite sides of the expansion plate 501, and the limiting grooves 502 slide in cooperation with the limiting plate 208; two symmetrical support baffles 503 are fixed at the bottom of the expansion plate 501, and a diagonal groove 504 is provided through one side of each support baffle 503, and the diagonal groove 504 slides in cooperation with the lever 405; two symmetrical sets of connecting vertical plates 209 are fixed between the U-shaped platform plate 207 and the operating table 2, and a guide vertical groove 211 is provided through one side of each set of connecting vertical plates 209; there are two connecting vertical plates 209 in each set, and they are symmetrically distributed on the left and right; the I-shaped slider 401 slides in cooperation with the guide vertical groove 211.

[0053] The specific application of this embodiment two is as follows: During the use of the entire construction operation platform, after the construction personnel climb onto the U-shaped platform 207, they can start the drive motor 110 to drive the bidirectional threaded screw 111 to rotate. During the rotation of the bidirectional threaded screw 111, the shear-type lifting platform 103 will move in a scissor-like motion. During the movement, through the sliding cooperation between the second slide groove 210 and the slide plate 113 and the sliding cooperation between the guide rod 205 and the sliding hole 114, the two symmetrically hinged sliding seats 112 at the top of the shear-type lifting platform 103 are driven to move in a scissor-like motion. The bottoms of the two chute 210s approach each other, thereby driving the entire operating platform 2 upward to reach the ground to be constructed in the traffic tunnel (the shear lifting platform 103 mentioned above is explained in the prior art publication CN217519558U, therefore the shear lifting platform 103 is prior art and will not be explained in detail here); as the operating platform 2 moves upward, the outward downward pressure of the inclined rotating arm 108 causes the rectangular vertical plate 115 fixed at the top of the inclined rotating arm 108 and the pin columns 116 fixed on opposite sides of the rectangular vertical plate 115 to be able to rotate in the groove 3 opened at the top of the lifting arm 3. 02 and the rotating groove 302 rotate relative to the pin holes 303 provided on the two inner side walls. During the rotation, under the rotational cooperation between the rotating hole 301 opened on one side of the lifting arm 3 and the rotating shaft 403 fixed on the inner wall of the U-shaped frame 402, the entire lifting arm 3 is driven to lift between the inclined rotating arm 108 and the U-shaped frame 402. This causes the I-shaped slider 401 to move upward inside the guide vertical groove 211, and finally causes the lever 404 fixed on one outer side of the U-shaped frame 402 and the lever 405 fixed on one side of the lever 404 to move upward inside the guide vertical groove 211. During the upward movement, the sliding engagement between the inclined groove 504 and the lever 405 causes the support baffle 503 to slide outward on the top of the operating platform 2. During the sliding process, the sliding engagement between the limiting groove 502 and the limiting plate 208 causes the extension piece 5 to extend outward between the operating platform 2 and the U-shaped platform plate 207. Thus, the rise of the construction operating platform drives the extension piece 5 to extend outward, increasing the operable space of the entire construction operating platform, bringing certain convenience to the construction personnel during the construction process, and eliminating the need to provide additional power for the extension piece 5, thereby improving work efficiency. Example 3

[0054] Please see Figure 1-13This embodiment three is an improvement on the first embodiment as follows: Specifically, a climbing ladder 212 is fixed to one side of a set of connecting vertical plates 209, and a ladder 213 is fixed to the bottom of the climbing ladder 212. A through hole 120 is opened on the top of the mobile vehicle 1 below the U-shaped frame 104. A hydraulic cylinder 117 is fixed to the top of the U-shaped frame 104. A chassis 118 is fixed to the telescopic end of the hydraulic cylinder 117. Several anti-slip balls 119 are fixed to the bottom of the chassis 118. Two symmetrical counterweights 101 are set on the top of the mobile vehicle 1.

[0055] The specific application of this embodiment four is as follows: the entire construction operation platform can be moved to the location where the traffic tunnel needs to be constructed. Before use, construction workers can enter the top of the construction operation platform by climbing ladder 212 and the ladder 213 fixed at the bottom of climbing ladder 212. During use, the two counterweights 101 set on the top of the mobile vehicle 1 can increase the weight on both sides of the entire construction operation platform, preventing the platform from tilting left and right during the left and right movement of the construction workers, thus increasing the safety of the construction process. In addition, after the entire construction operation platform has completed its ascent, the hydraulic cylinder 117 fixed at the top of the U-shaped frame 104 can be activated until the chassis 118 fixed at the extension end of the hydraulic cylinder 117 and the several anti-slip balls 119 fixed at the bottom of the chassis 118 come into contact with the construction site. Then, the hydraulic cylinder 117 is closed, thereby increasing the contact area between the entire construction operation platform and the construction site, increasing the stability of the entire construction operation platform during the construction process, preventing the entire construction operation platform from shaking during the construction work of the workers on the top of the construction operation platform, and increasing the safety of the construction process.
