Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a material transportation device for bridge construction. Background Art

[0002] In bridge construction projects, material transportation is a key link in ensuring construction progress and quality. Traditional methods of transporting bridge construction materials, such as manual handling or single-bucket lifting and transporting devices, have obvious limitations. Manual handling is not only inefficient, but also poses a major safety hazard when working at heights. Frequent up and down handling can easily lead to worker fatigue and increase the risk of accidents. Although the single-bucket lifting and transporting device can reduce the manpower burden to a certain extent, the single-time transportation volume is limited, and loading and unloading cannot be carried out at the same time. It is necessary to wait for the empty bucket to return before continuing to load. This leads to a long waiting time during the construction process, seriously affecting construction efficiency.

[0003] For this reason, a material transport device for bridge construction is proposed. Utility Model Content

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] like Figures 1 to 4 As shown, a material transportation device for bridge construction includes a base 1, and a loading component 3 for continuously conveying bridge construction materials is installed on the upper surface of the base 1. A support component 2 for supporting its own position is installed inside the base 1, and a positioning component 4 for adjusting the smoothness of material transportation is installed inside the loading component 3; specifically, by starting the loading component 3, multiple construction materials are driven to be transported to one side of the construction platform at a uniform speed, so that the staff can simultaneously add construction materials to the inside of the loading component 3 during the material retrieval process, thereby shortening the waiting time consumed in material transportation, and then improving the material transportation efficiency, thereby improving the practicality of the device; by starting the support component 2 to expand its own volume, the contact circumference between the bottom end of the device and the ground is increased, thereby avoiding the base 1 from tilting during use, thereby improving the stability of the device during use.

[0022] The loading assembly 3 includes a first side plate 301 and a second side plate 306. The first side plate 301 and the second side plate 306 are both mounted on the upper surface of the base 1. The first slider 303 and the second slider 307 are slidably connected to the interior of the first side plate 301 and the second side plate 306 respectively. The top of the first side plate 301 is mounted with a first motor 304. The output shaft of the first motor 304 passes through the top of the first side plate 301 and is mounted with a screw 302. The external thread of the screw 302 is connected to the interior of the first slider 303. The first slider 303 and the second slider 307 are internally connected to the rotating rod 305, and the second motor 308 is installed on the side of the second slider 307 away from the first side plate 301. The output shaft of the second motor 308 is installed at one end of the rotating rod 305. Four sets of second connecting sleeves 311 are installed on the outer end of the rotating rod 305. The second connecting sleeve 311 is rotatably connected to the transport box 316 on the side close to the second side plate 306. The first side plate 301 and the second side plate 306 are both provided with a card slot. The first and second sliders 303 and 307 are respectively slidably connected to the inside of the first side plate 301 and the second side plate 306. The inside of the first slider 303 and the second slider 307 are provided with through holes. The rotating rod 305 is rotatably connected to the inside of the through holes of the first slider 303 and the second slider 307. The outer surface of the rotating rod 305 is installed with a connecting sleeve 309. The upper and lower, front and back four sides of the connecting sleeve 309 are all installed with a first connecting sleeve 310. The inside of the first connecting sleeve 310 is installed with a second electric telescopic rod 317. The output end of the second electric telescopic rod 317 is installed inside the second connecting sleeve 311, and the second connecting sleeve 311 is slidably connected to the inside of the first connecting sleeve 310. A fixing rod 312 is installed on the side of the second connecting sleeve 311 close to the second side plate 306. A rotating bearing 313 is installed on the outer surface of the fixing rod 312. A connecting rod 314 is installed on the outer end of the rotating bearing 313. A U-shaped positioning rod 315 is installed at the bottom end of the connecting rod 314. The U-shaped positioning rod 315 is installed on the upper surface of the transport box 316.

[0023] Specifically, by starting the second motor 308 to drive the rotating rod 305 to drive the four groups of transport boxes 316 to rotate around the connecting sleeve 309, the four groups of transport boxes 316 can continuously transport building materials to the construction platform during use, and enable the staff to add construction materials to the upper material component 3 simultaneously during the material collection process, thereby shortening the waiting time consumed in material transportation and improving the material transportation efficiency; by starting the first motor 304 to drive the screw 302 to drive the first slider 303 to move up and down in the slot of the first side plate 301, the four groups of transport boxes 316 can be used. During the flipping process, the flipping height can be adjusted, and then the second electric telescopic rod 317 is started to push the second connecting sleeve 311 to drive the transport box 316 to move vertically or horizontally, so that the height of the four groups of transport boxes 316 can be synchronously adjusted according to the change of the construction platform height when in use, thereby expanding the scope of application of the device and improving the practicality of the device; the transport box 316 is installed at the outer end of the rotating bearing 313 using the connecting rod 314 and the U-shaped positioning rod 315, so that the transport box 316 is always perpendicular to the ground under the action of gravity, thereby preventing the material accumulated inside the transport box 316 from spilling.

[0024] The positioning assembly 4 includes a circular guide rail 401, which is installed on the side of the second slider 307 close to the transport box 316. The circular guide rail 401 is slidably connected to the four sets of slide rail members 402 on the side close to the transport box 316. A limiting rod 403 is installed on the side of the slide rail member 402 close to the first side plate 301. The end of the limiting rod 403 away from the slide rail member 402 is slidably connected to the inside of the transport box 316. A sliding groove is provided on the side of the transport box 316 away from the first side plate 301, and the end of the limiting rod 403 away from the slide rail member 402 is slidably connected to the slide groove of the transport box 316. Specifically, the slide rail member 402 is installed on one side of the transport box 316, so that the transport box 316 is driven when it rotates around the rotating rod 305. The dynamic limit rod 403 drives the slide rail member 402 to slide inside the circular guide rail 401, so that the positioning component 4 limits the flipping position of the transport box 316 during the rotation process, thereby preventing the transport box 316 from rotating at the lower end of the fixed rod 312 when rising, causing the construction materials accumulated inside the transport box 316 to spill, thereby improving the safety of the loading component 3 when in use; one end of the limit rod 403 is slidably connected to the inside of the transport box 316, so that the second connecting sleeve 311 drives the limit rod 403 to slide inside the slide groove of the transport box 316 when driving the transport box 316 to move upward or downward, thereby preventing the transport box 316 from being blocked by the limit rod 403 when adjusting the upward or downward movement.

[0025] A card slot is provided on the front of the transport box 316, and a protective cover plate 502 is hinged on the front of the transport box 316. The interior of the transport box 316 is slidably connected to an L-shaped limit block 501, and the front inner wall of the L-shaped limit block 501 abuts against the front of the protective cover plate 502. A card slot is provided on the front of the transport box 316, and the L-shaped limit block 501 is slidably connected to the inside of the card slot of the transport box 316; specifically, when the bottom of the inner wall of the top group of transport boxes 316 is adjusted and moved to the position of the upper end of the construction platform, by rotating the protective cover plate 502, the back of the protective cover plate 502 is rotated to a position parallel to the bottom of the inner wall of the transport box 316, and the top of the protective cover plate 502 is attached to the upper part of the construction platform. The surface allows workers to move the construction materials accumulated inside the transport box 316 to the construction table by pulling the materials, thereby reducing the time spent by workers in moving the materials accumulated inside the transport box 316; on the contrary, when the transport box 316 is transporting construction materials, by pushing the L-shaped limit block 501, the L-shaped limit block 501 is inserted into the slot of the transport box 316. At this time, the front inner wall of the L-shaped limit block 501 abuts against the front of the protective cover 502, so that the L-shaped limit block 501 limits the rotation position of the protective cover 502 at the front end of the transport box 316, thereby preventing the protective cover 502 from rotating when the transport box 316 transports construction materials.

[0026] The back of the protective cover 502 is rotatably connected to multiple sets of rotating rollers 6. A groove is provided on the back of the protective cover 502, and the multiple sets of rotating rollers 6 are rotatably connected in the groove of the protective cover 502. Specifically, by pushing the construction materials accumulated inside the transport box 316, when the materials move to the upper end of the multiple sets of rotating rollers 6, the moving construction materials drive the multiple sets of rotating rollers 6 to rotate. At this time, the multiple sets of rotating rollers 6 accelerate and drive the construction materials to slide on the upper end of the protective cover 502, thereby shortening the time spent by the staff in pushing out the construction materials accumulated inside the transport box 316.

[0027] The support assembly 2 includes a connecting plate 201, which is installed inside the base 1. First electric telescopic rods 203 are installed on the front and rear sides of the connecting plate 201. A fixed frame 202 is installed on the output end of the first electric telescopic rod 203. A slot is provided on the lower surface of the base 1. The connecting plate 201 is installed inside the slot of the base 1. Two sets of fixed frames 202 are slidably connected inside the slot of the base 1. Specifically, by starting the two sets of first electric telescopic rods 203, the two sets of fixed frames 202 are pushed to move outward in the slot of the base 1, so that the circumference of the bottom of the device and the ground is increased, thereby preventing the base 1 from tilting during use, thereby improving the stability of the device during use.

[0028] In summary: by starting the second motor 308 to drive the rotating rod 305 to drive the four groups of transport boxes 316 to rotate around the connecting sleeve 309, the four groups of transport boxes 316 can continuously transport building materials to the construction platform during use, and enable the staff to simultaneously add construction materials to the upper material component 3 during the material collection process; by rotating the protective cover 502, the back of the protective cover 502 is rotated to a position parallel to the bottom of the inner wall of the transport box 316, and the top of the protective cover 502 is attached to the upper surface of the construction platform, so that the staff can move the construction materials accumulated inside the transport box 316 to the construction table by pulling the materials.
