Description

Technical Field

[0001] The utility model relates to the technical field of counterweight mechanisms, in particular to a novel counterweight mechanism for bridge inspection. Background Art

[0002] In the field of bridge inspection and maintenance, counterweight mechanisms play a vital role. These mechanisms are widely used to simulate actual traffic loads in order to accurately evaluate the structural strength and performance of bridges. However, the design of traditional counterweight mechanisms is usually complicated, not only the operation is cumbersome, but the adjustment of the counterweight is also relatively fixed and lacks flexibility.

[0003] With the continuous advancement of bridge construction technology and the diversification of bridge types, traditional counterweight mechanisms have become difficult to adapt to the inspection needs of different types of bridges. In some cases, the counterweight may need to be adjusted more quickly to simulate the load conditions under different traffic modes; in other cases, a counterweight of a specific shape or size may need to be used to adapt to a specific bridge structure. However, traditional counterweight mechanisms often fail to meet these requirements, thus limiting their scope of application in actual work. Therefore, it is necessary to develop a new type of counterweight mechanism for bridge inspection. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-3 The utility model discloses a novel bridge inspection counterweight mechanism, which includes the following accessories:

[0032] A counterweight frame, used for carrying a counterweight block 4;

[0033] The counterweight block 4 is arranged in the counterweight frame and can be increased or decreased as needed to adjust the total counterweight;

[0034] A locking mechanism, used to fix the position of the counterweight 4 in the counterweight frame to prevent the counterweight 4 from moving during the detection process;

[0035] A suspension mechanism is used to suspend the counterweight mechanism under the bridge for load simulation.

[0036] The preferred solution of the above-mentioned novel counterweight mechanism for bridge inspection is:

[0037] The structure and function of the counterweight frame;

[0038] The counterweight frame is composed of an upper crossbeam 1, a lower crossbeam 2 and a vertical beam 3 to form a stable frame. The upper crossbeam 1 and the lower crossbeam 2 are arranged in parallel, and the vertical beam 3 connects the two to provide support for the counterweight block 4. The two sides of the vertical beam 3 are designed as counterweight grooves, and the counterweight block 4 is slidably installed in the counterweight grooves. This design allows the counterweight block 4 to be easily added or reduced on the vertical beam 3, thereby adjusting the total counterweight.

[0039] Sliding and fixing of the counterweight 4;

[0040] The counterweight block 4 is slidably connected to the slide grooves 6 on the upper beam 1 and the lower beam 2 through the slide rod 5 to achieve up and down sliding in the counterweight groove. This design simplifies the adjustment process of the counterweight block 4 and improves work efficiency. At the same time, the groove 10 design on the front side of the counterweight block 4 is convenient for the operator to grab and move.

[0041] Locking and unlocking of the locking mechanism;

[0042] The locking mechanism adopts a locking pin 8, which passes through the locking groove 7 of the counterweight block 4 through a threaded structure and is adapted to the locking hole 9 on the upper beam 1 or the lower beam 2. Rotating the locking pin 8 can lock and unlock the counterweight block 4, thereby ensuring the stability of the counterweight block 4 during the detection process.

[0043] Suspension and adjustment of suspension mechanism;

[0044] The suspension mechanism includes a lifting ring 12 and a steel wire rope 13. The lifting ring 12 is arranged at the top of the upper beam 1 and the bottom of the lower beam 2, and two rows are arranged on the upper beam 1 and the lower beam 2. The steel wire rope 13 is connected to the counterweight mechanism and the bridge through the lifting ring 12. This design allows the counterweight mechanism to be suspended under the bridge to simulate the actual traffic load. The two ends of the steel wire rope 13 are connected by a locking piece to adapt to bridges of different heights and ensure the stability of the connection of the steel wire rope 13. The locking piece in this embodiment can be a steel wire rope 13 buckle commonly used in the connection process of the steel wire rope 13.

[0045] The structure and function of the lock;

[0046] The locking device in this embodiment includes a locking rod 16 and a locking tube 15, which are adapted to each other through a threaded structure. The ends of the locking rod 16 and the locking tube 15 are rotatably mounted with a positioning rod 14. The steel bar and the positioning rod 14 are an integral structure. This design ensures a stable connection of the steel wire rope 13.

[0047] The structure of each component of the new bridge inspection counterweight mechanism is as follows:

[0048] Counterweight frame: It is composed of an upper crossbeam 1, a lower crossbeam 2 and a vertical beam 3, wherein the upper crossbeam 1 and the lower crossbeam 2 are arranged in parallel, and the vertical beam 3 connects the two to form a stable structure;

[0050] Counterweight block 4: Slidingly installed in the counterweight slots on both sides of the vertical beam 3 of the counterweight frame.

[0051] Adjustment: Add or remove the counterweight blocks 4 as needed to adjust the total counterweight to simulate different traffic loads;

[0052] Sliding mechanism: The upper and lower ends of the counterweight block 4 are slidably connected to the slide grooves 6 on the upper crossbeam 1 and the lower crossbeam 2 through the slide rod 5, so that the counterweight block 4 can be easily moved up and down in the counterweight groove.

[0053] Locking mechanism: A locking pin 8 is used to match the locking holes 9 on the upper crossbeam 1 and the lower crossbeam 2;

[0054] Working principle: When the counterweight 4 is adjusted to the desired position, the locking pin 8 penetrates the locking groove 7 and the locking hole 9 on the front side of the counterweight 4 through the threaded structure, thereby fixing the counterweight 4 in place.

[0055] Suspension mechanism: comprising a lifting ring 12 and a steel wire rope 13, wherein the lifting ring 12 is arranged at the top of the upper crossbeam 1 and the bottom of the lower crossbeam 2;

[0056] Working principle: The steel wire rope 13 connects the counterweight mechanism and the bridge through the lifting ring 12, so that the counterweight mechanism can be suspended under the bridge.

[0057] Function of the lock: The two ends of the steel wire rope 13 are connected by a lock, which includes a lock rod 16 and a lock tube 15, which are adapted through a threaded structure to ensure the stable connection of the steel wire rope 13. The ends of the lock rod 16 and the lock tube 15 are rotatably mounted with a positioning rod 14, and the steel bar and the positioning rod 14 are an integrated structure, which enhances the stability of the connection.

[0058] The design of the entire counterweight mechanism takes into account structural strength and stability, and adopts high-strength materials and reasonable structural design to ensure the safety and reliability of the counterweight mechanism during use. At the same time, the design of the locking mechanism and the suspension mechanism also fully considers safety factors, effectively avoiding unexpected situations that may occur during the detection process.
