Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically to a clamp for a climbing device. Background Technology

[0002] In cap beam construction, especially for cap beams with high piers or complex structures, the clamping method is a commonly used construction technique, characterized by its reliability and safety. With the continuous improvement of construction technology, using climbing devices based on the clamping method to lift cap beam clamps and other equipment from low to high positions has become an increasingly popular construction method among construction companies. Its biggest advantage is that cap beam clamps and other equipment can be installed at low positions, effectively reducing the risks of working at heights and improving construction efficiency.

[0003] The basic principle of a climbing device is that it uses upper and lower clamps to hold the bridge pier, utilizing the static friction between the clamps and the pier to achieve clamping. Power is then used to drive the upper and lower clamps to alternately push and lock, completing the step-by-step climbing process. Therefore, the clamps are an extremely important component of the climbing device, and their structure and function directly determine the use of the climbing device (such as safety and reliability).

[0004] Currently, in the known literature and patents, the clamps of various traditional clamps and climbing devices are mostly two-part types (including hydraulic and electric clamps). This means that the clamps need to be hoisted in sections to surround the pier, and then the two parts need to be connected manually using connecting bolts. Disassembly is the reverse, which is cumbersome. Utility Model Content

The whole unit is close to the pier column, and the opening and closing is automatically controlled by the opening and closing cylinder to surround or detach from the pier column. It is easy to install and disassemble, and can realize safe and efficient construction of the cap beam. It also has the characteristics of high automation and simple structure.

[0008] The three-lobed integrated clamp is mainly composed of module A, module B and module C, with module B and module C respectively hinged to module A.

[0009] The cylinder body of the opening and closing cylinder is hinged to module A, and the telescopic end is hinged to modules B and C. The opening and closing cylinder is used to drive modules B and C to rotate around the hinge point to open or close the three-lobed integrated clamp. The locking device is used to lock modules B and C a second time.

[0010] Furthermore, the panels of modules A, B, and C are all equipped with polyurethane adhesive strips, which can also be made of rubber or other composite materials.

[0011] The polyurethane adhesive strip is fixed to the panel with bolts.

[0012] Furthermore, the hinge holes of the opening and closing cylinder lugs on modules B and C are elongated holes, which allow modules B and C to rotate slightly inward during the locking process, thus preventing the opening and closing cylinders from bearing additional stress.

[0013] Furthermore, the locking device includes a hydraulic through-hole jack, a pull rod, and a nut, used to lock modules B and C after the clamps are closed.

[0014] Furthermore, the locking device also includes a pressure sensing unit, which is mounted on the vertical connecting plate of module C and is used to monitor the tension force in the locked state.

[0015] Furthermore, the hydraulic through-hole jack is fixed to the jack mounting sleeve of module B by set screws, and the pull rod passes through the vertical connecting plates of module B and module C and the hydraulic through-hole jack in sequence, and is mechanically locked by nuts.

[0016] Furthermore, the opening angle of the three-lobed integrated clamp is 0°-90°, and when closed, it forms a complete ring structure that fits against the surface of the pier column.

[0041] Example 1

[0042] See Figures 1-7 This embodiment discloses a clamp for a climbing device, including a three-lobed integrated clamp 1, an opening and closing hydraulic cylinder 3, and a locking device 4;

[0043] The three-lobed integrated clamp 1 is mainly composed of module A 11, module B 12 and module C 13. Module B 12 and module C 13 are respectively hinged to both sides of module A 11 through pins (hinged pins).

[0044] The cylinder body of the opening and closing cylinder 3 is hinged to module A 11 by a pin, and the telescopic end is hinged to module B 12 and module C 13. The opening and closing cylinder 3 is used to drive module B 12 and module C 13 to rotate around the hinge point to realize the opening or closing of the three-lobed integrated clamp; the locking device 4 is used to lock module B 12 and module C 13 a second time.

[0045] In this application, there are two opening and closing cylinders 3, which are connected to module B 12 and module C 13 respectively.

[0046] Furthermore, the panels of modules A 11, B 12 and C 13 are all provided with polyurethane adhesive strips, which can also be rubber or other composite materials in actual use.

[0047] The polyurethane adhesive strip is fixed to the panel with bolts.

[0048] Furthermore, the hinge holes of the opening and closing cylinder lugs on modules B 12 and C 13 and the opening and closing cylinder 3 are elongated holes, which are used for modules B 12 and C 13 to rotate slightly inward during the locking process to avoid the opening and closing cylinder 3 bearing additional stress.

[0049] Furthermore, the locking device 4 includes a hydraulic through-hole jack, a pull rod, and a nut, used to lock module B 12 and module C 13 after the clamp is closed.

[0050] Furthermore, the locking device 4 also includes a pressure sensing unit, which is mounted on the vertical connecting plate of module C 13 and is used to monitor the tension force in the locked state.

[0051] Furthermore, the hydraulic through-hole jack is fixed inside the jack mounting sleeve 128 of module B 12 by set screws, and the pull rod passes through the vertical connecting plate of module B 12, module C 13 and the hydraulic through-hole jack in sequence, and is mechanically locked by nuts.

[0052] Furthermore, the opening angle of the three-lobed integrated clamp 1 is 0°-90°, and when closed, it forms a complete ring structure that fits against the surface of the pier column 22.

[0053] This utility model mainly consists of a three-lobed integrated clamp 1, an opening and closing hydraulic cylinder 3, and a locking device 4. This utility model is mainly used in climbing devices (further used in cap beam construction). This clamp adopts a three-lobed integrated design, which does not need to be disassembled. The whole clamp is close to the pier 22, and the opening and closing is automatically controlled by the opening and closing hydraulic cylinder 3 to surround or detach from the pier 22. It has the advantages of convenient installation and disassembly, and can realize safe and efficient construction of cap beams. At the same time, it has the characteristics of high automation and simple structure.

[0054] To facilitate a better understanding of this invention by those skilled in the art, the following detailed description is provided in conjunction with specific implementation examples.

[0055] A climbing device includes a three-lobed integrated clamp 1, an opening and closing hydraulic cylinder 3, a locking device 4, etc.

[0056] The three-lobed integrated clamp 1 is composed of three independent parts, namely module A 11, module B 12, and module C 13;

[0057] Modules B12 and C13 are hinged to Module A11, and the opening and closing positions of the clamp are completed by the movement of Modules B12 and C13.

[0058] To increase the friction between the clamp and the pier 22, polyurethane strips are attached to the panel and secured with bolts. Considering potential deviations in the outer diameter of the pier, the polyurethane strips (rubber or other composite materials) are compressed and deformed during the clamping process to fill gaps, resulting in a larger and tighter contact area between the clamp and the pier. The bottom of the opening / closing cylinder 3 is mounted on module A 11, with its telescopic ends mounted on modules B 12 and C 13 respectively. During operation, the opening / closing cylinder 3 remains fixed on module A 11, and its extension and retraction drive the opening and closing of modules B 12 and C 13.

[0059] The locking device 4 includes a hydraulic through-hole jack, a pull rod, and a nut. The hydraulic through-hole jack is mounted on module B 12 (or module C 13) and secured with bolts. To monitor the locking status, a pressure sensing unit is installed on module C 13, which is in contact with it. Considering that the hydraulic through-hole jack is hydraulically driven and cannot maintain pressure for a long time without depressurization, a mechanical locking mechanism is added. That is, when the hydraulic through-hole jack is locked, module B 12 and module C 13 are mechanically locked by tightening the nut on the pull rod.

[0060] Furthermore, polyurethane strips are installed on the panel to increase the friction between the clamp and the pier column 22.

[0061] The locking device 4 employs a combination of hydraulic and mechanical locking. Once the clamp reaches the designated working position, the hydraulic locking switches to mechanical locking. The locking device 4 includes a pressure sensor to monitor the tension force.

[0062] In practice:

[0063] Reference Figures 1-8 The clamp of the climbing device described in this application will be further explained.

[0064] The specific structure of Module A11 is as follows:

[0065] See Figure 3 Module A 11 is welded together from panel A112, hinge ear plate A113, opening and closing ear plate A114, lifting cylinder ear plate A115, horizontal plate A116, and vertical plate A117. Polyurethane plate A111 is connected to the panel by fastener 2 bolts.

[0066] The specific structure of Module B12 is as follows:

[0067] See Figure 5 Module B 12 is welded together from panel B122, hinge ear plate B123, opening / closing cylinder ear plate B124, lifting cylinder ear plate B125, horizontal plate B126, vertical plate B127, jack mounting sleeve 128, and vertical connecting plate B129. Polyurethane plate B121 is connected to the panel by fastener bolts. Jack mounting sleeve 128 has threaded holes for set screws to be installed to secure the hydraulic through-hole jack. The vertical connecting plate has holes larger than the tie rod for the tie rod to pass through. The hole through which the opening and closing cylinder lug B124 is hinged to the opening and closing cylinder 3 is an elongated hole. When the locking device 4 is tightened, module B12 and module C13 will rotate slightly inward. After the opening and closing cylinder 3 extends to its full position, it will retract slightly, so that its hinge pin 21 is in the middle of the elongated hole. This elongated hole can ensure that there is swing space between the hinge pin 21 of the opening and closing cylinder 3 and the cylinder 3, thereby preventing module B12 and module C13 from being unable to rotate slightly due to being tightened by the opening and closing cylinder 3.

[0068] The specific structure of Module C13 is as follows:

[0069] See Figure 6The pressure sensor sleeve 139 is constructed by welding together a panel C132, a hinged lug plate C133, an opening / closing cylinder lug plate C134, a lifting cylinder lug plate C135, a horizontal plate C136, a vertical plate C137, a vertical connecting plate C138, and a pressure sensor mounting sleeve 1391. The polyurethane plate C131 is bolted to the panel. The pressure sensor sleeve 139 consists of the pressure sensor mounting sleeve 1391 and a sleeve cover plate 1392. The pressure sensor mounting sleeve 1391 is welded to the vertical connecting plate C138, and the sleeve cover plate 1392 is bolted to the sensor mounting sleeve. The vertical connecting plate C138 has a hole larger than the pull rod for the pull rod to pass through. The hole where the opening and closing cylinder ear plate C134 is hinged to the opening and closing cylinder 3 is an elongated hole. When the locking device 4 is tightened, module B 12 and module C 13 will rotate slightly inward. After the opening and closing cylinder 3 extends to its full position, it will retract slightly, so that its hinge pin 21 is in the middle of the elongated hole. This elongated hole can ensure that there is swing space between the hinge pin 21 of the opening and closing cylinder 3, thereby avoiding the opening and closing cylinder 3 from tightening and causing module B 12 and module C 13 to be unable to rotate slightly.

[0070] The climbing device's clamp consists of a three-part integrated clamp 1 (module A 11, module B 12, module C 13), fasteners (including the hinge pin 21 of the opening and closing cylinder 3 and the hinge pin 21 shaft of module A, B, C, and D), the opening and closing cylinder 3, and the locking device 4.

[0071] In the working state, module A 11 is initially held firmly against the pier 22 and remains stationary. Modules B 12 and C 13 are hinged to module A 11, with hinge pins 21 used at the hinge points. The cylinder body of the opening and closing cylinder 3 is hinged to module A 11 at the cylinder body end, and the telescopic ends are hinged to modules B 12 and C 13 respectively.

[0072] During operation, the extension and retraction of the opening and closing hydraulic cylinder 3 drives the opening and closing of module B 12 and module C 13.

[0073] The clamp closing process is as follows:

[0074] The clamp is divided into three integrated sections (Module A 11, Module B 12, and Module C 13). Module A 11 remains stationary, while Modules B 12 and C 13 are hinged to Module A 11. The opening and closing of the clamp is accomplished by the extension and retraction of the hydraulic cylinder 3. To ensure a more secure clamping grip on the pier 22, the friction of the contact surfaces needs to be increased; therefore, polyurethane panels are attached to the panels of Modules A 11, B 12, and C 13. After the clamp is closed, Modules B 12 and C 13 are locked using a locking device 4. The locking device 4 has both hydraulic and mechanical locking functions. During the lifting process of the climbing device, hydraulic locking can be achieved using a through-hole hydraulic jack; after the climbing device reaches its position, the hydraulic locking is converted to a mechanical locking method using a tie rod nut, thereby maximizing the reliability and safety of the climbing device construction. This clamp features a simple structure, reliable locking, and good opening and closing effect.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
