Description

Technical Field

[0001] This utility model relates to the field of municipal technology, and in particular to a road construction frame and road construction fence. Background Technology

[0002] Municipal construction fences are commonly used in construction sites of ordinary roads and highways for road separation, area enclosure for safety isolation, traffic diversion, guidance, or for maintaining order in special celebrations or sports and entertainment events. They can also be used to protect and safeguard equipment and facilities in factories and public places.

[0003] Existing road construction scaffolding and fencing are inconvenient to install and dismantle, time-consuming and labor-intensive, and once installed, they are very difficult to move. This leads to reduced construction efficiency and increased labor and time costs. Utility Model Content

[0004] This utility model solves the problems of road construction frame and road construction fence being inconvenient, time-consuming and labor-intensive to install and dismantle, and very inconvenient to move once installed. Therefore, it provides a road construction frame and road construction fence.

[0005] This utility model is achieved by the following technical solution: a road construction frame and road construction fence, including a lifting mechanism, a connecting mechanism is provided on the top of the lifting mechanism, and a plug-in mechanism is provided on one side of the connecting mechanism;

[0006] The lifting mechanism includes a mounting platform, a first gear is rotatably connected inside the mounting platform, a connecting cylinder is fixedly connected to the bottom of the first gear, a lead screw is threadedly connected to the inner wall of the connecting cylinder, a lifting plate is fixedly connected to the bottom of the lead screw, limiting grooves are opened on the left and right sides of the inner wall of the mounting platform, a universal wheel is fixedly connected to the bottom of the lifting plate, a second gear is rotatably connected inside the mounting platform, and a handle is fixedly connected to one side of the second gear.

[0007] Through the above technical solution, the limiting groove plays a guiding and limiting role in the up and down movement of the lifting plate, preventing the lifting plate from deviating or shaking during the movement, and ensuring the stable operation of the lifting plate.

[0008] As a further improvement to the above solution, the bottom of the mounting platform is provided with a groove, and the top of the mounting platform is provided with a screw hole.

[0009] As a further improvement to the above scheme, the first gear meshes with the second gear, and the two sides of the lifting plate are slidably connected to the inner wall of the limiting groove.

[0010] As a further improvement to the above solution, the connecting mechanism includes a threaded rod, a support rod fixedly connected to the top of the threaded rod, a sliding groove formed on the surface of the support rod, a connecting rod inserted into the top of the support rod, and a slot formed on the surface of the connecting rod.

[0011] With the above technical solution, there are four sliding grooves and four locking slots, located at the front and rear ends and left and right sides of the support plate and connecting rod, respectively. The sliding grooves and locking slots allow construction personnel to add lower and upper guardrail plates as needed.

[0012] As a further improvement to the above solution, the threaded rod is located inside the mounting platform, the surface of the threaded rod is threaded to the inner wall of the mounting platform, the top of the support rod is provided with a groove, and the sliding groove and the retaining groove are connected.

[0013] Through the above technical solution, the slot cooperates with the upper fence panel to firmly fix the upper fence panel to the connecting rod, ensuring that the upper fence panel will not easily fall off during the use of the fence, thus guaranteeing the protective effect of the fence.

[0014] As a further improvement to the above solution, the insertion mechanism includes a lower guardrail plate, and an upper guardrail plate is inserted and connected to the top of the lower guardrail plate.

[0015] As a further improvement to the above solution, the lower guardrail is located on one side of the support rod, one side of the lower guardrail is slidably connected to the inner wall of the sliding groove, the top of the lower guardrail is provided with a groove, and one side of the upper guardrail is inserted into the upper guardrail.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features casters; turning the handle rotates the second gear. Since the first and second gears mesh, the first gear rotates, causing the connecting cylinder to rotate as well. Because the lead screw is threaded into the inner wall of the connecting cylinder, the lead screw drives the lifting plate downwards. During this process, the sides of the lifting plate slide against the inner wall of the limiting groove, thus allowing the casters to move downwards. This makes the device easier to move. When frequent adjustments to the fence position are needed at the construction site, workers can easily push the fence to the designated location, greatly improving construction efficiency and saving manpower and time costs.

[0018] This utility model uses a support rod and a connecting rod, with two mounting platforms placed on either side of the lower guardrail panel. The support rod is then threaded to the mounting platform using threaded rods. Next, the lower guardrail panel is slid into the inner wall of the support rod along the sliding groove on its surface. Then, the bottom of the connecting rod is inserted into the groove at the top of the support rod, and one side of the upper guardrail panel is embedded into the slot on the surface of the connecting rod, while the bottom of the upper guardrail panel is inserted into the groove at the top of the lower guardrail panel. Finally, the other side of the upper guardrail panel is inserted into the slot of the connecting rod on the other side, and this connecting rod is inserted into the top of the corresponding support rod, completing the installation. In terms of ease of installation, the connection method of each component is simple and direct, allowing construction personnel to quickly complete the connection without complex tools or professional skills, greatly shortening installation time and improving the efficiency of pre-construction preparation.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0027] Please combine Figure 1-5The road construction frame and road construction fence of this embodiment include a lifting mechanism 1, a connecting mechanism 2 is provided on the top of the lifting mechanism 1, and a plugging mechanism 3 is provided on one side of the connecting mechanism 2.

[0028] The lifting mechanism 1 includes a mounting platform 101. A first gear 102 is rotatably connected inside the mounting platform 101. A connecting cylinder 103 is fixedly connected to the bottom of the first gear 102. A lead screw 104 is threadedly connected to the inner wall of the connecting cylinder 103. A lifting plate 105 is fixedly connected to the bottom of the lead screw 104. Limiting grooves 106 are provided on the left and right sides of the inner wall of the mounting platform 101. A caster wheel 107 is fixedly connected to the bottom of the lifting plate 105. A second gear 108 is rotatably connected inside the mounting platform 101. A handle 109 is fixedly connected to one side of the second gear 108. Rotating the handle 109 causes the second gear 108 to rotate. Because the first gear 102 and the second gear 108 mesh with each other, the first gear 102 rotates accordingly, and the connecting cylinder 103 also rotates along with the first gear 102. Since the lead screw 104 is threadedly connected to the inner wall of the connecting cylinder 103, the lead screw 104 drives the lifting plate 105 to move downward. During this process, the two sides of the lifting plate 105 slide on the inner wall of the limiting groove 106, thereby enabling the caster wheel 107 to move downward, making the device move more conveniently.

[0029] The bottom of the mounting platform 101 has a groove, and the top of the mounting platform 101 has a screw hole.

[0030] The first gear 102 meshes with the second gear 108, and the two sides of the lifting plate 105 are slidably connected to the inner wall of the limiting groove 106.

[0031] The connecting mechanism 2 includes a threaded rod 201, with a support rod 202 fixedly connected to the top of the threaded rod 201. A sliding groove 203 is formed on the surface of the support rod 202, and a connecting rod 204 is inserted into the top of the support rod 202. A slot 205 is formed on the surface of the connecting rod 204. Two mounting platforms 101 are placed on either side of the lower guardrail plate 301. The support rod 202 is threadedly fixed to the mounting platform 101 via the threaded rod 201. Next, the lower guardrail plate 301 is slid into the inner wall of the support rod 202 along the sliding groove 203 on its surface. Then, the bottom of the connecting rod 204 is inserted into the groove at the top of the support rod 202, and one side of the upper guardrail plate 302 is inserted into the slot 205 on the surface of the connecting rod 204, while the bottom of the upper guardrail plate 302 is inserted into the groove at the top of the lower guardrail plate 301. Next, insert the other side of the upper fence panel 302 into the slot 205 of the connecting rod 204 on the other side, and insert the connecting rod 204 on the other side into the top of the corresponding support rod 202.

[0032] The threaded rod 201 is located inside the mounting platform 101. The surface of the threaded rod 201 is threaded to the inner wall of the mounting platform 101. The top of the support rod 202 is provided with a groove, and the sliding groove 203 and the slot 205 are connected.

[0033] The insertion mechanism 3 includes a lower guardrail plate 301, and an upper guardrail plate 302 is inserted and connected to the top of the lower guardrail plate 301.

[0034] The lower guardrail plate 301 is located on one side of the support rod 202. One side of the lower guardrail plate 301 is slidably connected to the inner wall of the sliding groove 203. A groove is provided on the top of the lower guardrail plate 301. One side of the upper guardrail plate 302 is inserted into the upper guardrail plate 302.

[0035] The implementation principle of a road construction fence according to an embodiment of this application is as follows: First, take two mounting platforms 101 and place them on both sides of the lower fence plate 301. Secure the support rod 202 to the mounting platform 101 with threads via threaded rods 201. Next, slide the lower fence plate 301 along the sliding groove 203 on the surface of the support rod 202 into the inner wall of the support rod 202. Then, insert the bottom of the connecting rod 204 into the groove at the top of the support rod 202, and then embed one side of the upper fence plate 302 into the slot 205 on the surface of the connecting rod 204, while simultaneously inserting the bottom of the upper fence plate 302 into the groove at the top of the lower fence plate 301. Afterward, insert the other side of the upper fence plate 302 into the slot 205 of the connecting rod 204 on the other side, and insert the connecting rod 204 on the other side into the top of the corresponding support rod 202.

[0036] Finally, turn handle 109 to rotate the second gear 108. Since the first gear 102 meshes with the second gear 108, the first gear 102 rotates accordingly, and the connecting cylinder 103 also rotates with it. Because the lead screw 104 is threadedly connected to the inner wall of the connecting cylinder 103, the lead screw 104 drives the lifting plate 105 downwards. During this process, the two sides of the lifting plate 105 slide against the inner wall of the limiting groove 106, thereby allowing the casters 107 to move downwards, making the device easier to move. When the fence position needs frequent adjustments at the construction site, construction workers can easily push the fence to the designated location, greatly improving construction efficiency and saving manpower and time costs.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
