Description

Technical Field

[0001] The invention relates to the technical field of transportation devices, in particular to a construction material transportation device for highway maintenance. Background Art

[0002] Highway maintenance plays an indispensable role in ensuring traffic safety and extending the service life of highways. In the process of highway maintenance, the transportation of construction materials is a frequent and important work link, which is directly related to the efficiency and cost of maintenance projects. However, there are often various problems in the transportation of construction materials. For example, waterproofing membranes are key materials for highway waterproofing and moisture-proofing and are widely used in highway maintenance. The traditional transportation method of waterproofing membranes mainly relies on manual handling or simple carts.

[0003] During manual handling, the waterproofing membrane itself is heavy, such as the common SBS modified asphalt waterproofing membrane, which can weigh up to 30-65 kg per roll. This makes the handling work extremely labor-intensive and requires a lot of physical strength from the workers, and it is easy to cause fatigue and injury to the workers. At the same time, the low efficiency of manual handling has seriously restricted the progress of highway maintenance projects.

[0004] Although simple carts have reduced the burden of manpower to a certain extent, they still have many limitations. Such carts have a simple structure and lack a placement mechanism that is compatible with the rolls. During transportation, the waterproof rolls are prone to rolling and sliding, which may not only cause material damage and affect the quality of the project, but also pose a threat to the safety of personnel and equipment at the construction site. In addition, the carrying capacity of simple carts is limited, and it is difficult to meet the one-time transportation needs of a large number of waterproof rolls. Multiple round trips are required, which increases time and transportation costs. Summary of the invention

A placing piece 36 is installed on the outer surface of the connecting rod 35. The placing piece 36 is arranged between a group of locking kits 34. The placing piece 36 is used to place building materials. A supporting piece 37 is installed at the bottom of the placing piece 36. The supporting piece 37 supports and buffers the placing piece 36.

A locking tooth block 343 is fixedly mounted on the surface of the rotating bar 342. The locking tooth block 343 is engaged and adapted with the locking toothed ring 332. The locking tooth block 343 and the locking toothed ring 332 are used to fix the position of the locking kit 34 on the fixed rod 331 to ensure that the width of the placement piece 36 remains stable after adjustment. A bearing 345 is fixedly installed on one side of the rotating bar 342 away from the shaft end. The bearing 345 is arranged opposite to the locking tooth block 343.

By rotating the clamping bolt 346, the locking tooth block 343 is clamped with the locking tooth ring 332 to fix the locking kit 34. The placement member 36 includes an arc-shaped support plate 361, which is rotatably mounted on the outer surface of the connecting rod 35. The arc-shaped support plate 361 is convenient for adjusting the angle to better fit the shape of the material. A rubber protective strip 362 is fixedly mounted on the upper surface of the arc-shaped support plate 361. The rubber protective strip 362 can protect the placed building materials and prevent the surface of the materials from being damaged. A sliding groove 363 is provided on the side of the arc-shaped support plate 361 away from the connecting rod 35, and an arc-shaped connecting plate 364 is slidably mounted inside the sliding groove 363. Two arc-shaped supporting plates 361 form a group, and one group of arc-shaped supporting plates 361 is arranged opposite to each other, and the arc-shaped connecting plate 364 is arranged between the group of arc-shaped supporting plates 361. A connecting spring 365 is fixedly installed inside the slide groove 363, and the connecting spring 365 is fixedly connected to both sides of the arc-shaped connecting plate 364. The connecting spring 365 can automatically adjust the distance between the two arc-shaped supporting plates 361 according to the material diameter, and play a buffering role at the same time. The supporting members 37 are evenly distributed at the bottom of the arc-shaped connecting plate 364. When the building material is placed on the placement member 36, the arc-shaped supporting plate 361 of the placement member 36 will automatically rotate and adjust the angle according to the shape of the building material to better fit the building material. Since a group of arc-shaped supporting plates 361 arranged opposite to each other are connected by the arc-shaped connecting plate 364, the building material is further stabilized. The support member 37 includes a sleeve 371, which is fixedly installed in the middle of the bottom of the arc-shaped connecting plate 364. A first buffer spring 373 is fixedly installed at the top of the inner cavity of the sleeve 371. The first buffer spring 373 plays a role of buffering and shock absorption.

A suction cup 374 is fixedly installed at the bottom of the support seat 372. The suction cup 374 is set at the top of the inner cavity of the protective shell 1. The suction cup 374 is adsorbed on the protective shell 1 to increase the overall stability of the placement mechanism 3 and prevent the placement piece 36 from shaking during transportation.

[0024] The third embodiment is based on the first and second embodiments. Figures 1 to 15 As shown, the fixing structure 6 is installed on the inner wall of the protective shell 1, and the fixing structure 6 fixes and buffers the building materials; The fixing structure 6 includes a slide rod 601 and a fixing plate 602. The slide rod 601 is fixedly installed at the four corners of the inner wall of the protective shell 1. The fixing plate 602 is fixedly installed on both sides of the inner wall of the protective shell 1. The fixing plate 602 is arranged directly above the slide rod 601. There are four slide rods 601, and two slide rods 601 form a group. A slide plate 603 is slidably connected between a group of slide rods 601. A fixed elastic band 604 is fixedly connected between the slide plate 603 and the fixing plate 602. The fixed elastic bands 604 are staggered. First magnetic blocks 607 are fixedly installed on both sides of the top of the slide plate 603. A second buffer spring 609 is fixedly installed on the top of the inner cavity of the slide rod 601. The bottom of the second buffer spring 609 is fixedly connected to a second magnetic block 60 8. The second magnetic block 608 is magnetically adapted to the first magnetic block 607. A snap-in hole 605 is provided at the bottom of the outer side surface of the slide rod 601. Receiving grooves 611 are provided on both sides of the slide plate 603. A snap-in spring 612 is fixedly installed inside the receiving groove 611. The other end of the snap-in spring 612 is fixedly connected to a snap-in rod 613. The snap-in rod 613 is snap-fitted to the snap-in hole 605. When the building materials are placed, the slide plate 603 is slid to make the snap-in rod 613 snap-fitted to the snap-in hole 605 at the bottom of the outer side surface of the slide rod 601. The staggered fixed elastic bands 604 fix the building materials. The higher the building materials are piled up, the greater the elastic force of the fixed elastic bands 604, and the better the fixing effect, which greatly reduces the time cost and transportation cost.

[0025] A push block 614 is fixedly installed on one side of the bottom of the slide plate 603, and a door-blocking rod 606 is slidably installed on the bottom of the slide groove rod 601. The door-blocking rod 606 is set at the feed end of the device, and a slider 610 is fixedly installed on the outer surface of the door-blocking rod 606. The push block 614 is squeezed and adapted with the slider 610. When the slide plate 603 slides downward, the push block 614 pushes the slider 610 to drive the door-blocking rod 606 to move toward the inside of the protective shell 1. When the clamping rod 613 is clamped with the clamping hole 605 at the bottom of the outer side of the slide groove rod 601, the door-blocking rod 606 just does not contact the loading plate 2. At this time, the loading plate 2 can be closed normally. This design prevents the situation where the loading plate 2 is closed before the fixing structure 6 is fixed.

[0026] When in use, the device is moved to the storage location of building materials through the pulleys 7 at the four corners of the bottom of the protective shell 1, and the clamping bolts 346 are rotated to make the locking tooth block 343 disengage from the locking tooth ring 332, and the rotating bar 342 rotates around the rotating shaft, and the sliding rod sleeve 341 stops sliding after moving to a suitable distance, and the width of the placement member 36 is adjusted, and the clamping bolts 346 are rotated to make the locking tooth block 343 engage with the locking tooth ring 332, so as to fix the locking kit 34; Put down the loading plate 2 to form an inclined loading channel. The staff pushes the building materials along the loading plate 2 to the placement mechanism 3. The anti-slip strips 4 on the surface of the loading plate 2 can effectively prevent the materials from sliding during the loading process, ensuring the safety of loading. When the building materials are placed on the placement member 36, the arc-shaped support plate 361 of the placement member 36 will automatically rotate and adjust the angle according to the shape of the building materials to better fit the building materials. Since a group of oppositely arranged arc-shaped support plates 361 are connected by an arc-shaped connecting plate 364, the building materials are further stabilized. The sleeve 371 of the support member 37 is fixed at the middle of the bottom of the arc-shaped connecting plate 364, and the first buffer spring 373 in the sleeve 371 is connected to the support seat 372. The suction cup 374 at the bottom of the support seat 372 is adsorbed on the top of the inner cavity of the protective shell 1, which not only plays a role in buffering and shock absorption, but also increases the overall stability of the placement mechanism 3, and plays a supporting role for the placement member 36; When the building materials are placed, the slide plate 603 is slid to make the clamping rod 613 engage with the clamping hole 605 at the bottom of the outer side of the slide rod 601, and the staggered fixed elastic bands 604 fix the building materials. The higher the building materials are piled, the greater the elastic force of the fixed elastic bands 604, and the better the fixing effect. When the slide plate 603 slides downward, the push block 614 pushes the slide block 610 to drive the door stop rod 606 to move into the protective shell 1. When the clamping rod 613 is clamped with the clamping hole 605 at the bottom of the outer side of the slide slot rod 601, the door stop rod 606 and the loading plate 2 just do not come into contact. At this time, the loading plate 2 can be closed normally. This design prevents the situation where the fixing structure 6 is not fixed and the loading plate 2 is closed; During transportation, the protective shell 1 prevents the material from sliding backwards, and the foam pad 8 on the inner wall of the protective shell 1 can provide buffering protection for the material that hits the protective shell 1, thereby preventing the material from being damaged.
