Description

Technical Field

[0001] This invention relates to the field of building construction engineering, and specifically to a channel steel construction device. Background Technology

[0002] In urban public works projects, especially municipal road projects and urban sewage pipeline renovation projects, a large amount of foundation pit excavation work is involved. Foundation pit support is a necessary safety guarantee measure for foundation pit excavation and is the bottom line for ensuring safe production. For foundation pits and trenches with shallow excavation depth, channel steel support is often used. However, conventional channel steel construction technology often uses brute force to drive the piles during construction, and violent pile extraction often occurs during removal. Because the steel cables on the original construction machinery are insufficient to restrain the swaying of the channel steel during pile driving and extraction, the stability of the channel steel is poor, causing significant disturbance to the underground soil and potentially damaging underground pipelines, underground structures, etc. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a channel steel construction device to solve the problems of poor stability of existing channel steel during pile driving and extraction, large disturbance to underground soil, and potential damage to underground structures.

[0004] The technical solution to achieve the above objectives is:

[0005] This invention provides a channel steel construction device for driving and extracting piles of channel steel. The channel steel construction device includes:

[0006] Connector;

[0007] The machine head connected to the connecting seat has a plug groove formed on the machine head for the end of the channel steel to be inserted, and through holes communicating with the plug groove are provided on both sides of the machine head.

[0008] A connecting rod, which can pass through the through hole of the machine head and through the corresponding channel steel, is provided with a groove on one side wall near the machine head; and

[0009] A locking mechanism is provided on the side wall of the machine head and adapted to the slot. The locking mechanism locks the slot to restrict the movement of the connecting rod when the connecting rod passes through the through hole of the machine head.

[0010] The construction device of the present invention locks the channel steel during the driving and extraction of the channel steel, thereby minimizing the shaking of the channel steel during construction. This improves the construction safety factor from driving to extraction and has little impact on surrounding buildings.

[0011] A further improvement of the channel steel construction device of the present invention is that the locking mechanism includes a movable and adjustable fastener disposed on the inner side of the side wall of the machine head, an installation plate disposed on the inner side of the side wall of the machine head and corresponding to the fastener, a first spring supporting and connected between the installation plate and the fastener, and a first electromagnet disposed opposite to the installation plate and the fastener.

[0012] When the first electromagnet is energized, it generates magnetism and attracts each other, so that the fastener moves closer to the mounting plate and compresses the first spring;

[0013] After the first electromagnet is de-energized, the first spring pushes the fastener to move away from the mounting plate and thus engages with the slot of the connecting rod.

[0014] A further improvement of the channel steel construction device of the present invention is that a sliding groove is provided on the inner side of the side wall of the machine head corresponding to the fastener, and the sliding groove is located between the through hole on the machine head and the mounting plate;

[0015] The fastener is slidably installed in the groove.

[0016] A further improvement of the channel steel construction device of the present invention is that the locking mechanism includes a movable and adjustable fastener disposed on the inner side of the side wall of the machine head, an installation plate disposed on the inner side of the side wall of the machine head and corresponding to the fastener, a second spring supporting and connected between the installation plate and the fastener, and a second electromagnet correspondingly disposed on the fastener and the side wall of the machine head near the through hole.

[0017] The second spring applies a spring force to the fastener to bring the fastener closer to the mounting plate;

[0018] When the second electromagnet is energized, it generates magnetism and attracts the other electromagnet, causing the fastener to move away from the mounting plate and stretch the second spring, so that the fastener can be inserted into the slot of the connecting rod.

[0019] A further improvement of the channel steel construction device of the present invention is that the slot is an arc-shaped slot;

[0020] The locking mechanism includes a locking element that is adapted to the arcuate groove.

[0021] A further improvement of the channel steel construction device of the present invention is that it also includes a hoisting mechanism provided on the connecting seat, the hoisting mechanism being connected to the machine head and capable of lowering or raising the machine head.

[0022] A further improvement of the channel steel construction device of the present invention is that the hoisting mechanism includes a winch mounted on the connecting seat, a first pulley mounted on the connecting seat, and a second pulley mounted on the winch head;

[0023] The rope on the winch passes around the first pulley and the second pulley and is fixed to the connecting seat. The winch is used to control the lowering or raising of the winch head by winding and releasing the rope. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] See Figure 1 This invention provides a channel steel construction device to address the safety hazards and significant environmental impact associated with channel steel piling and extraction. It is primarily applied to channel steel construction in foundation pit support. During construction, a self-locking rigid connection ensures the stability of the channel steel during driving and extraction, eliminating the risk of tipping or detachment and avoiding quality issues such as verticality deviation. After extraction, the channel steel is smoothly lowered using a hoisting mechanism, completely eliminating the safety risks associated with the channel steel's tilting or swaying during construction. The channel steel construction device of this invention will be described below with reference to the accompanying drawings.

[0031] See Figure 1 This image shows a front view of the channel steel construction device of the present invention. (See also...) Figure 2 This image shows a top view of the machine head in the channel steel construction device of the present invention. The following is in conjunction with... Figure 1 and Figure 2 The present invention will describe the channel steel construction device.

[0032] like Figure 1 and Figure 2As shown, the channel steel construction device of the present invention is used for pile driving and pile extraction operations of channel steel. The channel steel construction device includes a connecting seat 21, a machine head 22, a connecting rod 23, and a locking mechanism 24. The machine head 22 is connected to the connecting seat 21. The machine head 22 has a insertion groove for inserting the end of the channel steel 12. The two sides of the machine head 22 are provided with through holes 221 communicating with the insertion groove. The connecting rod 23 can pass through the through hole 221 of the machine head 23 and pass through the corresponding channel steel 12. The connecting rod 23 has a slot on one side wall near the machine head 22. The locking mechanism 24 is provided on the side wall of the machine head 22 and is adapted to the slot. The locking mechanism 24 locks the slot when the connecting rod 23 passes through the through hole of the machine head 22 to restrict the movement of the connecting rod 23.

[0033] The present invention uses a connecting rod 23 to limit and fix the channel steel 12 in the insertion slot of the machine head 22, and a locking mechanism 24 to prevent the connecting rod 23 from detaching from the machine head 22, thereby ensuring that the channel steel 12 will not fall off and ensuring construction safety.

[0034] In one specific embodiment of the present invention, such as Figure 1 As shown, during construction, the connecting seat 21 can be connected to the end of the excavator's mechanical arm 11, and the excavator's mechanical arm 11 applies force to the connecting seat 21 and the excavator head 22 to achieve pile driving and pile extraction operations.

[0035] In one specific embodiment of the present invention, such as Figure 2 and Figure 4 As shown, the locking mechanism 24 includes a movable and adjustable fastener located on the inner side of the side wall of the head 22, a mounting plate located on the inner side of the side wall of the head 22 and corresponding to the fastener, a first spring supporting the connection between the mounting plate and the fastener, and a first electromagnet located on the mounting plate and the fastener respectively.

[0036] When the first electromagnet is energized, it generates magnetism and attracts each other, so that the fasteners approach the mounting plate and compress the first spring;

[0037] After the first electromagnet is de-energized, the first spring pushes the fastener to move away from the mounting plate and thus engages in the slot of the connecting rod 23.

[0038] Specifically, the power supply to the first electromagnet can be controlled by a remote control device. Before inserting the connecting rod, the first electromagnet is powered on to keep the fastener away from the through hole 221 on the machine head 22. After inserting the connecting rod, the first electromagnet is de-powered to allow the fastener to snap into the slot on the connecting rod 23.

[0039] Furthermore, the inner side of the side wall of the machine head 22 is provided with a sliding groove corresponding to the fastener, and the sliding groove is located between the through hole on the machine head and the mounting plate;

[0040] The fastener slides within the groove. The groove serves to limit and guide the movement of the fastener, allowing it to move and adjust along the groove's direction.

[0041] Furthermore, the fastener is also tightly attached to the side of the channel steel, so that the channel steel and the machine head form a rigid whole.

[0042] In one specific embodiment of the present invention, the locking mechanism 24 includes a movable and adjustable fastener disposed on the inner side of the side wall of the machine head 22, a mounting plate disposed on the inner side of the side wall of the machine head and corresponding to the fastener, a second spring supporting and connected between the mounting plate and the fastener, and a second electromagnet corresponding to the fastener and the position of the side wall of the machine head near the through hole.

[0043] The second spring applies a spring force to the fastener to bring it closer to the mounting plate;

[0044] When the second electromagnet is energized, it generates magnetism and attracts the other electromagnet, causing the fastener to move away from the mounting plate and stretch the second spring, so that the fastener can be inserted into the slot of the connecting rod.

[0045] Specifically, the second electromagnet can be powered on and off via a remote control. Before inserting the connecting rod, the second electromagnet is de-energized to keep the fastener away from the through hole on the machine head. After inserting the connecting rod, the second electromagnet is powered on to allow the fastener to snap into the slot of the connecting rod.

[0046] In one specific embodiment of the present invention, the slot is an arc-shaped slot, and the fastener is an arc-shaped component adapted to the arc-shaped slot.

[0047] In one specific embodiment of the present invention, such as Figure 1 , Figure 3 and Figure 5 As shown, it also includes a hoisting mechanism 25 disposed on the connecting seat 21. The hoisting mechanism 25 is connected to the machine head 22 and can lower or raise the machine head 22.

[0048] Specifically, the hoisting mechanism 25 includes a winch 251 mounted on the connecting seat 21, a first pulley 253 mounted on the connecting seat 21, and a second pulley mounted on the machine head;

[0049] The rope 252 on the winch 251 passes around the first pulley 253 and the second pulley and is fixed to the connecting seat 21. The winch 251 controls the lowering or raising of the machine head 22 by winding and unwinding the rope 252.

[0050] A rope 252 is wound around the winch 251. The end of the rope 252 passes over the first pulley 253, then over the second pulley, and is then fixedly connected to the connecting seat 21 near the first pulley 253. When the winch 251 lowers the rope 252, the channel steel 12 and the winch head 22 move vertically downward under the action of gravity, thus realizing the hoisting and lowering of the channel steel 12.

[0051] In one specific embodiment of the present invention, an anti-slip rubber ring is provided between the connecting rod 23 and the through hole 221, and the anti-slip rubber ring is sleeved on the connecting rod 23.

[0052] The channel steel construction device of this invention employs a self-locking rigid connection structure during construction to ensure the stability of the channel steel during installation and removal, eliminating the risk of tipping or detachment and avoiding quality problems such as verticality deviation. After the channel steel is removed, the installed hoisting mechanism can slowly and steadily lower it, completely eliminating the safety risks caused by the channel steel's own tilting and swaying during construction.

[0053] The channel steel construction device of the present invention can be completed by one operator from pile driving to pile extraction and then stacking the channel steel to the designated material storage yard. No auxiliary personnel are required, which optimizes the allocation of on-site human resources and reduces construction cost.

[0054] The channel steel construction device of the present invention eliminates the existing method of driving and pulling out channel steel by large-scale vibration and brute force, reduces the disturbance to the underground soil during the driving and pulling out of channel steel, and minimizes the impact on underground pipelines and surrounding buildings and other structures.

[0055] The channel steel construction device of the present invention, due to its rigid force-bearing structure, can better transmit mechanical force. Its structure itself has increased efficiency compared with the traditional channel steel construction process. At the same time, the channel steel can be installed and stacked quickly, accurately and stably according to the plan by relying on the hoisting mechanism, which optimizes the construction deployment, saves the time cost of material turnover, and speeds up the construction progress.

[0056] The channel steel construction device of the present invention has higher construction efficiency and less impact on underground pipelines and surrounding buildings during construction. Compared with traditional methods, it is more adaptable to various complex, narrow and geologically challenging terrain environments.

[0057] The channel steel construction device of the present invention does not cause mechanical damage to the channel steel during use, protects the turnover material to the maximum extent, improves the service life of the material, and saves material costs significantly in the long run.

[0058] This invention employs a mutually locking mechanism during construction, resulting in excellent mechanical force transmission and high efficiency. Simultaneously, the hoisting mechanism ensures the stability of all structural connections during construction and stacking of the channel steel, preventing mechanical damage and saving material costs. After use, the channel steel can be stacked stably and efficiently, optimizing construction deployment. This comprehensively improves the economic benefits of channel steel construction. The rigid locking structure under double fixing minimizes channel steel swaying during construction, significantly increasing the safety factor from driving and removing piles to stacking and removal. This structure has minimal impact on surrounding buildings during construction and shortens the time required, allowing for precise control of the channel steel stacking position. Compared to existing structures, this channel steel construction device is more versatile and better suited for channel steel construction in complex terrains. The new channel steel construction device is simple to operate, requiring only one person, optimizing human resource allocation and training costs. The interconnected yet individually disassembled structural components facilitate maintenance and upkeep.

[0059] The construction process of the channel steel construction device of the present invention is as follows:

[0060] Insert the connecting rods into the machine head and the circular hole in the channel steel in sequence;

[0061] The remote locking mechanism locks the machine head and channel steel together at the slots on both sides of the connecting rod, making the machine head and channel steel a rigid whole.

[0062] After the fixing is completed, the connecting seat is connected to the excavator's mechanical arm. Through the action of the excavator's mechanical arm, the excavator head vibrates up and down in a regular, small amplitude, which loosens the soil under the channel steel until the channel steel can be driven into the soil smoothly. The same operation is used when pulling out the pile.

[0063] When the channel steel is completely removed and suspended in the air, the hoisting mechanism can be activated to slowly lower the channel steel.

[0064] After stacking the channel steel in a convenient location for turnover and transportation, the locking mechanism can be released. The locking mechanism will automatically spring back to its original position, and the connecting rod can be pulled out to proceed to the next construction process.

[0065] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
