Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel frames for concrete pouring, specifically a combined steel frame structure for full-section road pouring. Background Technology
[0002] The combined steel frame used for full-section road construction constructs an overall support framework through pre-embedded columns, ground beams, and an adjustable support system, enabling one-time full-section concrete pouring from the base slab to the side walls and top slab. This structure places the steel frame foundation directly at the bottom of the structural base slab, eliminating the need for layered construction and effectively removing longitudinal construction joints in the side walls that are present in traditional methods, thus reducing the risk of water seepage at its source.
[0003] There are many requirements for pavement thickness in current road construction. Roads of different functions and grades need to be matched with corresponding thicknesses to meet the needs of load-bearing capacity and durability. However, the modular steel frame used in existing road construction has obvious limitations. Its height is designed with fixed specifications, which means that a steel frame of a certain specification can only be adapted to pavement construction of a specific thickness and cannot cope with different engineering scenarios. Furthermore, the installation process of the steel frame's supporting frame is cumbersome, requiring many bolts or welding for connection and fixation, which consumes a lot of manpower and time. Moreover, recycling and reusing it will generate a lot of work. Utility Model Content
[0004] The purpose of this invention is to provide a sand milling device for removing rust from cathode steel rods in aluminum electrolysis cells, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined steel frame structure for full-section road casting, comprising a casting steel frame body, wherein the surface of the casting steel frame body is provided with a lifting mechanism for controlling its own height, the inner cavity of the casting steel frame body is provided with a support mechanism for supporting itself, and the inner cavity of the casting steel frame body is provided with a limiting groove for restricting some components of the support mechanism.
[0006] Preferably, the lifting mechanism includes a sleeve fixed to the surface of the cast steel frame body, a sliding rod sliding in the inner cavity of the sleeve, a plurality of first springs fixed on the inner wall of the sliding rod, a locking block fixed at the other end of the first spring, the locking block sliding on the inner wall of the sliding rod, and a plurality of limiting holes opened on the surface of the sleeve, the locking block sliding on the inner wall of the limiting holes.
[0007] Preferably, the support mechanism includes a plurality of traction ropes fixed to the surface of the sleeve, a push block fixed to the other end of the traction rope, a pulley sliding on the surface of the traction rope, a rotating shaft fixed on the surface of the pulley, and the rotating shaft can guide the movement of the traction rope through a guiding action. A support block is fixed on the surface of the push block, and a second spring is fixed on the surface of the push block. The other end of the second spring is fixed to the inner wall of the limiting groove.
[0008] Preferably, the limiting holes are spaced at the same interval and are 2 cm apart.
[0009] Preferably, the second spring is made of high-strength stainless steel and works in conjunction with the traction rope.
[0010] Preferably, the traction rope is made of high-strength fiber rope, which can cooperate with the second spring.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The purpose of this utility model is to provide a combined steel frame structure for full-section road casting. Through the design of the lifting mechanism, the height of the casting steel frame body can be flexibly adjusted within a certain range according to actual needs. Whether it is to deal with the casting operation of thin road surface or to meet the construction requirements of thick road, the mechanism can be adapted by free lifting, effectively solving the problems of fixed height and single applicability of traditional steel frames. At the same time, under the coordinated action of the support mechanism, when the lifting mechanism drives the steel frame body to adjust the height, the support frame will simultaneously perform telescopic movements. This mechanism ensures that the steel frame can obtain relatively stable support force regardless of its height. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 As shown, a combined steel frame structure for full-section road casting includes a casting steel frame body 1, which includes a base and an adjustable top seat. A lifting mechanism 2 is provided on the surface of the casting steel frame body 1. The lifting mechanism 2 includes a sleeve 21 fixed to the surface of the casting steel frame body 1. A sliding rod 22 slides in the inner cavity of the sleeve 21. Several first springs 23 are fixed on the inner wall of the sliding rod 22. A locking block 24 is fixed to the other end of the first spring 23. The locking block 24 slides on the inner wall of the sliding rod 22. Several limiting holes 25 are opened on the surface of the sleeve 21. The limiting holes 25 are opened at the same interval and are 2 cm apart, which is suitable for most dimensions of road surface casting at the current stage to ensure construction requirements.
[0016] The locking block 24 slides on the inner wall of the limiting hole 25. When the height of the cast steel frame body 1 needs to be adjusted, after confirming the height, the worker first holds the locking block 24 and then pulls the top seat upward. With continuous pulling, the first spring 23 inside and the locking block 24 cooperate to pop out and adjust it to the corresponding position. At this time, the locking block 24 will be locked into the corresponding limiting hole 25. After both sides are fixed, the height adjustment and fixation of the cast steel frame body 1 is completed. After use, simply push the locking block 24 back to compress the first spring 23 and retract the sliding rod 22 back into the sleeve 21 to complete the recycling, which is convenient for the next use and greatly increases the practicality and applicability of this support frame.
[0017] It can be used to control the cross-sectional height of the cast steel frame body 1. The inner cavity of the cast steel frame body 1 is provided with a support mechanism 3, which can provide vertical support as the height of the cast steel frame body 1 is continuously increased, so as to ensure that 45° support is provided at all times during support. The inner cavity of the cast steel frame body 1 is provided with a limit groove 4. The support mechanism 3 includes several pulling ropes 31 fixed to the surface of the sleeve 21. The other end of the pulling rope 31 is fixed with a push block 34. The pulling rope 31 is made of high-strength fiber rope, and has high rigidity and no elasticity. To ensure increased wear resistance during use, and because it is inelastic, it better restricts the position of the push block 34. A pulley 32 slides on the surface of the traction rope 31, and a rotating shaft 33 is fixed to the surface of the pulley 32. The rotating shaft 33 guides the movement of the traction rope 31 through a guiding action. A support block 35 is fixed to the surface of the push block 34, and a second spring 36 is fixed to the surface of the push block 34. The second spring 36 is made of high-strength stainless steel and can cooperate with the traction rope 31 to maintain its strength in humid construction environments. It is not easily rusted or damaged. The other end of the second spring 36 is fixed to the inner wall of the limiting groove 4. When the lifting mechanism 2 controls the casting steel frame body 1 to rise and fall, the traction rope 31 is used to continuously rise under the drive of the sleeve 21. With the assistance of the pulley 32, it pulls the push block 34 to move horizontally. Under the action of external force, it simultaneously pushes the support block 35 fixed to it to continuously extend outward until the sleeve 21 stops, providing the required horizontal support force for the casting steel frame body 1. When retracting, as the sleeve 21 descends, the second spring 36 continuously pulls, pulling the push block 34 to pull back inward, driving the support block 35 back into the inner cavity of the casting steel frame body 1 to complete the retraction and release of the support block 35. It can be retracted and released automatically without additional operation, reducing the workload of workers and improving work efficiency. It can limit the sliding of some parts in the support mechanism 3. The height of the casting steel frame body 1 can be adjusted arbitrarily to meet the needs of various road surfaces. The adaptive support mechanism 3 can provide the support force required for different heights.
[0018] Working principle: When the height of the cast steel frame body 1 needs to be adjusted, the worker holds the top seat and pulls it upwards. As the sleeve 21 rises, the locking block 24 is ejected by the first spring 23 after reaching the corresponding position, and it is inserted into the corresponding limiting hole 25 to complete the fixation, thus completing the height adjustment of the cast steel frame body 1. After the work is completed, simply push the locking block 24 to disengage it from the limiting hole 25, then press the top seat to lower it, and finally restore it to its original position to ensure the next use. This setting not only greatly increases its applicability, but also... To achieve reuse, and at the same time, due to the traction of the traction rope 31, with the assistance of the pulley 32, the push block 34 is driven to move continuously in the horizontal direction, causing its support block 35 to protrude, so as to ensure the horizontal support force of the cast steel frame body 1. After the work is completed, as the sleeve 21 continues to descend, the tension on the traction rope 31 gradually decreases. At this time, the second spring 36, which has been taut, will pull the push block 34 to return to its original position, and drive the support block 35 back into the interior of the cast steel frame body 1, so as to complete the storage of the support block 35, thereby facilitating transportation.
