Description

Technical Field

[0001] The utility model relates to the technical field of road paving construction, in particular to a paving elevation device. Background Art

[0002] When paving, the paver needs a longitudinal parallel reference line of the road surface elevation. According to the height of the parallel reference line, the paver uses the paver height sensor to adjust the extension and retraction of the paver cylinder in real time, and always keeps the height of the rear ironing plate of the asphalt concrete paver higher than the loose paving coefficient of the road surface. The flatness and elevation of the paving are mainly determined by the height of the steel wire. The precise height of the steel wire is determined by the stability of the column and the height adjustment accuracy.

[0003] In the prior art, steel bars are often inserted on both sides of the road, and steel wire ropes are tied to the outside of the steel bars as parallel reference lines. However, pre-embedded steel bars and tying steel wire ropes to the outside of the steel bars require the cooperation of multiple personnel, and it is not easy to adjust the height of the steel wire ropes, the efficiency is low, and the wire ropes are easily damaged. Therefore, a paving elevation device is proposed to solve the above problems. Utility Model Content

[0008] The beneficial effect of the utility model is as follows: the device is placed equidistantly on one side of the paving area, and the construction workers adjust the height of the device in turn. The construction workers squat and step on the circular bottom plate with their feet, and use an electric wrench to drive the lifting and adjusting assembly to move, thereby raising the lifting threaded rod, and the lifting threaded rod slides in the columnar sleeve. At the same time, the height measuring assembly is observed until the lifting threaded rod drives the top support block to rise to a suitable height, thereby installing the square tube between the two adjacent devices, so that the square tube is slidably sleeved on the outside of the top support block, and when the quick-connect buckle assembly enters the through hole on the outside of the square tube, the quick-connect buckle assembly locks the top support block and the square tube. The paving elevation device has the advantages of quick installation and easy adjustment of the height of the parallel reference line.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] The beneficial effect of adopting the above further scheme is that the electric wrench drives the hexagonal shaft to rotate, which in turn drives the worm to rotate, and the worm engages with the internal threaded worm wheel, so that the internal threaded worm wheel rotates, and the force generated by the rotation of the thread drives the lifting threaded rod to rise, that is, drives the top support block to rise to an appropriate height.

[0012] Furthermore, the quick-connect buckle assembly includes a fixed shaft, a spring sheet, a wedge-shaped buckle and a pressing rod, the interior of the top support block is fixedly connected with the fixed shaft, the outer side of the fixed shaft is fixedly connected with the spring sheet in contact with the front and rear walls of the inner cavity of the top support block, the two ends of the spring sheet away from the fixed shaft are respectively fixedly connected with wedge-shaped buckles extending to the front and rear sides of the top support block, the wedge buckles are movably connected to the top support block, and the front and rear sides of the top support block are slidably connected with pressing rods extending into the interior thereof and in contact with the spring sheet;

[0013] Furthermore, through holes adapted to the wedge-shaped buckles are provided on the front and rear sides of both ends of the square tube.

[0014] The beneficial effect of adopting the above further scheme is that, in the process of making the square tube be slidably sleeved on the outside of the top support block, when the square tube contacts the wedge-shaped buckle, the inner wall of the square tube cooperates with the wedge-shaped surface of the wedge-shaped buckle, so that the wedge-shaped buckle moves toward the inside of the top support block, and the spring piece undergoes elastic deformation. When the wedge-shaped buckle is aligned with the through hole, the spring piece restores the elastic deformation, and then the wedge-shaped buckle enters the through hole, that is, the wedge-shaped buckle locks the top support block and the square tube. When it is necessary to separate the square tube from the top support block, the pressing rod is pressed to move the pressing rod toward the inside of the top support block, and the opposite side of the pressing rod causes the spring piece to undergo elastic deformation, and then drives the wedge-shaped buckle to separate from the through hole, so that the square tube can be separated from the top support block.

[0015] Furthermore, the height measuring assembly includes a slider, a height rod, an observation hole, a pointer and a magnifying lens. The left side of the assembly shell is fixedly connected with a slider, the interior of the slider is slidably connected with a height rod fixedly connected to the bottom of the top support block and adapted to the lifting threaded rod, an observation hole adapted to the height rod is opened on the front side of the slider, a pointer is fixedly connected to the inner wall of the observation hole, a magnifying lens adapted to the height rod is fixedly connected to the interior of the observation hole, and a digital scale is engraved on the front side of the height rod.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that the digital scale is engraved on the front side of the height rod. Before the lifting threaded rod of the device is raised, the scale that the pointer is aligned with through the observation hole is the starting scale. The starting scale is the vertical distance from the top support block to the ground. When the lifting threaded rod drives the top support block to rise, the top support block drives the height rod to slide upward on the slider, and it is observed through the observation hole until the pointer points to the appropriate scale on the outside of the height rod, and then the lifting of the lifting threaded rod is stopped. During this process, the magnifying glass will amplify the observed scale numbers, thereby facilitating observation by construction personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the embodiment, Figure 1-6 A paving elevation device is provided. The utility model comprises a circular base plate 1 and a square tube 2. A columnar sleeve 3 is fixedly connected to the top of the circular base plate 1. A lifting threaded rod 4 extending to the top of the columnar sleeve 3 is slidably connected inside the columnar sleeve 3. An assembly shell 5 located on the outside of the lifting threaded rod 4 is fixedly connected to the top of the columnar sleeve 3. A lifting adjustment component 6 threadedly connected to the lifting threaded rod 4 and extending to the front side thereof is provided inside the assembly shell 5. A top support block 7 adapted to the square tube 2 is fixedly connected to the top of the lifting threaded rod 4. A quick-connect buckle component 8 symmetrically distributed on the left and right and extending to the front and rear sides thereof is provided inside the top support block 7. A through hole 9 adapted to the buckle component 8 is opened on the outside of the square tube 2. A height measuring component 10 fixedly connected to the bottom of the top support block 7 is provided on the left side of the assembly shell 5.

[0026] The lifting adjustment assembly 6 includes an internal threaded worm wheel 601, an internal hexagonal rotating shaft 602 and a worm 603. The internal part of the assembly shell 5 is rotatably connected to the internal threaded worm wheel 601 located on the outside of the lifting threaded rod 4 and threadedly connected to the lifting threaded rod 4. The internal part of the assembly shell 5 is rotatably connected to the internal hexagonal rotating shaft 602 extending to the front side thereof. The external side of the internal hexagonal rotating shaft 602 is fixedly connected to the worm 603 meshing with the internal threaded worm wheel 601.

[0027] The electric wrench drives the hexagonal shaft 602 to rotate, and then drives the worm 603 to rotate. The worm 603 is meshed with the internal thread worm wheel 601, so that the internal thread worm wheel 601 rotates. The force generated by the rotation of the thread drives the lifting thread rod 4 to rise, that is, drives the top support block 7 to rise to a suitable height;

[0028] The quick-connect buckle assembly 8 includes a fixed shaft 801, a spring piece 802, a wedge-shaped buckle 803 and a pressing rod 804. The interior of the top support block 7 is fixedly connected with the fixed shaft 801, the outer side of the fixed shaft 801 is fixedly connected with the spring piece 802 that contacts both the front and rear walls of the inner cavity of the top support block 7, and both ends of the spring piece 802 away from the fixed shaft 801 are respectively fixedly connected with wedge-shaped buckles 803 extending to the front and rear sides of the top support block 7, the wedge-shaped buckles 803 are movably connected to the top support block 7, and the front and rear sides of the top support block 7 are slidably connected with pressing rods 804 that extend into the interior and contact the spring piece 802.

[0029] The front and rear sides of both ends of the square tube 2 are provided with through holes 9 adapted to the wedge-shaped buckles 803;

[0030] In the process of sliding the square tube 2 onto the outside of the top support block 7, when the square tube 2 contacts the wedge-shaped buckle 803, the inner wall of the square tube 2 cooperates with the wedge-shaped surface of the wedge-shaped buckle 803, so that the wedge-shaped buckle 803 moves toward the inside of the top support block 7, and the spring piece 802 undergoes elastic deformation. When the wedge-shaped buckle 803 is aligned with the through hole 9, the spring piece 802 recovers its elastic deformation, and then the wedge-shaped buckle 803 enters the through hole 9, that is, the wedge-shaped buckle 803 locks the top support block 7 with the square tube 2. When it is necessary to separate the square tube 2 from the top support block 7, the pressing rod 804 is pressed to move the pressing rod 804 toward the inside of the top support block 7, and the opposite side of the pressing rod 804 causes the spring piece 802 to undergo elastic deformation, and then drives the wedge-shaped buckle 803 to separate from the through hole 9, so that the square tube 2 can be separated from the top support block 7.

[0031] The height measuring assembly 10 comprises a slider 101, a height rod 102, an observation hole 103, a pointer 104 and a magnifying lens 105. The slider 101 is fixedly connected to the left side of the assembly shell 5. The height rod 102 fixedly connected to the bottom of the top support block 7 and adapted to the lifting threaded rod 4 is slidably connected inside the slider 101. The observation hole 103 adapted to the height rod 102 is opened on the front side of the slider 101. The inner wall of the observation hole 103 is fixedly connected to the pointer 104. The inside of the observation hole 103 is fixedly connected to the magnifying lens 105 adapted to the height rod 102. The front side of the height rod 102 is engraved with a digital scale.

[0032] The digital scale is engraved on the front side of the height rod 102. Before the lifting threaded rod 4 of the device is raised, the scale that the pointer 104 is aligned with through the observation hole 103 is the starting scale. The starting scale is the vertical distance from the top support block 7 to the ground. When the lifting threaded rod 4 drives the top support block 7 to rise, the top support block 7 drives the height rod 102 to slide upward on the slider 101. It is observed through the observation hole 103 until the pointer 104 points to the appropriate scale outside the height rod 102, and then the lifting of the lifting threaded rod 4 is stopped. During this process, the magnifying glass 105 will amplify the observed scale numbers to facilitate observation by construction personnel.

[0033] Working principle:

[0034] The first step: the device is placed at an equal distance on one side of the paving area, and the construction workers adjust the height of the device in turn. The construction workers squat down and step on the circular bottom plate 1 with their feet, and use the electric wrench to drive the hexagonal shaft 602 to rotate, and then drive the worm 603 to rotate. The worm 603 is meshed with the internal thread worm wheel 601, so that the internal thread worm wheel 601 rotates. The force generated by the rotation of the thread drives the lifting thread rod 4 to rise, and the lifting thread rod 4 slides in the columnar sleeve 3, that is, drives the top support block 7 to rise to a suitable height. During this process, the top support block 7 drives the height rod 102 to slide upward on the slider 101, and observes through the observation hole 103 until the pointer 104 points to the appropriate scale outside the height rod 102, and then stops the lifting of the lifting thread rod 4. During this process, the magnifying glass 105 amplifies the observed scale numbers, so as to facilitate the construction workers' observation;

[0035] Step 2: Install the square tube 2 between two adjacent devices, so that the square tube 2 is slidably sleeved on the outer side of the top support block 7. When the square tube 2 contacts the wedge buckle 803, the inner wall of the square tube 2 cooperates with the wedge surface of the wedge buckle 803, so that the wedge buckle 803 moves toward the inside of the top support block 7, and the spring piece 802 undergoes elastic deformation. When the wedge buckle 803 is aligned with the through hole 9, the spring piece 802 recovers its elastic deformation, and then the wedge buckle 803 enters the through hole 9. The wedge buckle 803 locks the top support block 7 with the square tube 2, and the square tube 2 can be regarded as a reference line.

[0036] Step 3: When it is necessary to separate the square tube 2 from the top support block 7, press the pressing rod 804 to move the pressing rod 804 toward the inside of the top support block 7. The opposite side of the pressing rod 804 causes the spring sheet 802 to undergo elastic deformation, thereby driving the wedge-shaped buckle 803 to separate from the through hole 9, thereby separating the square tube 2 from the top support block 7.
