Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a telescopic platform for the construction of variable cross-section piers. Background Technology

[0002] Variable cross-section pier construction is commonly used in mountainous highways, bridges spanning deep valleys, and high-pier structures. The core challenges lie in adapting to the gradual change in cross-section, ensuring safety during high-altitude operations, and controlling construction efficiency. As the pier height increases, the cross-section gradually decreases. After construction, other equipment needs to be installed, especially elevators. During elevator installation, the attachment points need to be adjusted according to the changing parameters of the pier cross-section to ensure the distance between the elevator guide rails and the pier adapts to the changing cross-section. In other words, elevator construction requires maintaining a vertical installation position. As the pier grows taller, the greater the distance, necessitating a construction access platform that can accommodate these changes in spacing. Traditional construction platforms cannot adapt to these variations, posing construction risks and inconvenience. Utility Model Content

Detailed Implementation

[0028] like Figure 1-7 In this invention, a telescopic platform for the construction of variable cross-section piers includes a support plate 2 that can move along the central axis of a base 1. Multiple railings 3 are detachably and symmetrically arranged on the support plate 2, and a safety passage 4 is formed between two opposing railings 3. The construction needs can be met by changing the relative position of the support plate 2 within the base 1.

[0029] Because the cross-section of the variable cross-section pier gradually decreases with increasing height, the attachment position of the elevator needs to be adjusted according to the geometric parameters of the cross-section during the initial design phase. This results in the attachment points not coinciding on the ground. Therefore, during elevator installation, the length of the construction passage needs to be changed to ensure safe and rapid installation by construction personnel. The telescopic platform in its fully retracted state is as follows: Figure 1 As shown, the telescopic platform is in the following state when d is open: Figure 5 As shown in the diagram, construction workers can adjust the position of the support plate 2 relative to the base 1 as needed to meet construction requirements. Since the support plate 2 is embedded in the base 1, it ensures convenient use and the safety of construction workers.

[0030] In a preferred embodiment, the base 1 includes a C-shaped frame 101, with symmetrical sliding grooves 104 on both sides of the C-shaped frame 101, and multiple rollers 9 on the bottom of the support plate 2, which are slidably connected to the sliding grooves 104.

[0031] The C-frame 101 structure is simple and provides a window for the movement of the support plate 2, avoiding interference. At the same time, the rotation of the roller 9 is used to make the contact between the support plate 2 and the base 1 a rolling friction, which ensures smooth movement and avoids jamming.

[0032] In a preferred embodiment, a plurality of first horizontal plates 102 are provided parallel to each other at the bottom of the C-shaped frame 101. The plurality of first horizontal plates 102 are connected to each other by a first vertical plate 103. A first threaded hole 105 is provided through the C-shaped frame 101, and a screw 7 for limiting the roller 9 is inserted in the first threaded hole 105.

[0033] By setting the first horizontal plate 102 and the first vertical plate 103, the stability, rigidity and load-bearing capacity of the base 1 structure are ensured. At the same time, the overall hollow design reduces the weight and makes it easier to move. Multiple rollers 9 cooperate with each other, making maintenance convenient. When the support plate 2 needs to be moved, the screw 7 in the first threaded hole 105 is removed to release the restriction on the roller 9. When the support plate 2 is moved into place, the screw 7 in the first threaded hole 105 is inserted to constrain and limit the roller 9. The cooperation of multiple screws 7 in the first threaded hole 105 improves safety and reliability.

[0034] like Figure 11 In the preferred embodiment, the bottom of the support plate 2 is provided with a fourth threaded hole 205, the screw 7 passes through the roller 9 and the fourth threaded hole 205, the side wall of the roller 9 is attached to the inner side of the slide groove 104, and the lower side of the slide groove 104 is also provided with a support plate 106.

[0035] The support plate 106 increases the contact area between the base 1 and the ground, thus providing more stable support while ensuring the structural strength of the groove 104 of the base 1.

[0036] like Figure 9 In the preferred embodiment, the top of the support plate 2 is provided with multiple square tubes 203, the railing 3 includes a main rib 301, the inner side of the main rib 301 is provided with multiple connecting ribs 302, and the lower side of the main rib 301 is inserted into the square tube 203.

[0037] The square tube 203 ensures the convenience of use for the railing 3. Its internal cross-sectional area is larger than the circular outer diameter of the main rib 301, making operation more convenient. At the same time, it can also ensure that the main rib 301 can still be installed even if there are errors in its manufacturing process.

[0038] In the preferred embodiment, a ring plate 10 is provided at the lower part of the main rib 301, a third threaded hole 204 is provided through the square tube 203, a screw 7 is inserted into the third threaded hole 204, and the outer side of the screw 7 is attached to the top of the ring plate 10.

[0039] By setting the screw 7 and the ring plate 10 together, the problem of the main rib 301 moving in the height direction is avoided. Preferably, the third threaded hole 204 is set opposite each other, and the number is set to two, so that the ring plate 10 is constrained at two positions and the overall force is balanced.

[0040] In a preferred embodiment, the outer side of the C-shaped frame 101 is also provided with an ear plate 108, and the bottom of the support plate 2 is also provided with a plurality of second horizontal plates 201. The second horizontal plates 201 are provided with a fifth threaded hole 206, and the ear plate 108 and the second horizontal plates 201 are detachably provided with foot pads 5.

[0041] The pad 5 includes a screw, a ball head set at the bottom of the screw, and a rubber pad connected to the ball head by a ball joint. This ensures that the base 1 and the support plate 2 can be stably supported as needed, avoiding uneven force on the bottom of the base 1 and the support plate 2 when the ground is uneven, thus preventing them from being in a "seesaw" state and avoiding safety risks for construction workers when walking.

[0042] like Figure 8 , 10 In the preferred embodiment, a support plate 8 is detachably provided on the first vertical plate 103, and a plurality of balls 802 are provided on the support plate 8. A second vertical plate 202 is provided at the bottom of the support plate 2, and the balls 802 are supported at the bottom of the second vertical plate 202.

[0043] By setting the support plate 8, the overall load-bearing capacity is further improved, the operation of the support plate 2 is more stable, and the support plate 2 is more convenient to remove. That is, even if the rollers 9 on both sides completely fail, it can still be moved easily, and the risk of the rollers 9 failing easily under heavy load is avoided.

[0044] In a preferred embodiment, the first vertical plate 103 is provided with a second threaded hole 107, the support plate 8 is provided with a mounting hole 803, the screw 7 passes through the mounting hole 803 and the second threaded hole 107, and the bottom of the support plate 8 is provided with a plurality of pads 801.

[0045] The above-mentioned design ensures that the support plate 8 can be easily installed and removed, and can be adjusted as needed. At the same time, there are gaps between the multiple pads 801, which reduces the weight.

[0046] In a preferred embodiment, a limiting plate 6 is connected to one side of the C-shaped frame 101 by screws 7. A through hole 109 is provided through the side wall of the C-shaped frame 101. The limiting plate 6 includes a stop bar 601 and a baffle 603. The stop bar 601 has a sixth threaded hole 602 on both sides. The baffle 603 has a first magnetic surface 604 and a second magnetic surface 605 on both sides.

[0047] When the support plate 2 is no longer in use and needs to be stored, it is completely retracted into the base 1. At the same time, the limiting plate 6 is installed into the notch of the C-shaped frame 101 with screws to prevent the support plate 2 from sliding out. When the support plate 2 needs to be opened, the limiting plate 6 is removed. After the support plate 2 is moved to the designed position, the end of the support plate 2 and the top surface of the base 1 are fixed by the first magnetic surface 604 and the second magnetic surface 605 to further ensure that the connection between the two is firm and reliable.

[0048] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
