Description

Technical Field

[0001] This utility model belongs to the field of tunnel construction equipment, specifically relating to a trolley detection device and a trolley. Background Technology

[0002] In the construction of some long tunnels, in order to shorten the construction period, inclined shafts are set up to increase the number of working faces. Originally a single construction direction can be opened up to new construction points through inclined shafts, and multiple working faces can be constructed at the same time, which greatly speeds up the tunnel breakthrough and effectively shortens the overall construction time.

[0003] However, the inclined shaft itself has an inclination angle, which causes uneven weight distribution when equipment operates on it. The center of gravity of the equipment is prone to shift, especially during lifting and excavation operations, where the change in the center of gravity is more pronounced. When the center of gravity exceeds the equipment's support range, it can easily lead to overturning. On the other hand, the geological conditions of inclined shafts are often complex, with problems such as broken rocks, loose soil, and faults. This can lead to unstable support foundations for the equipment. During operation, uneven settlement may occur at the support points, thereby disrupting the equipment's balance and causing overturning accidents.

[0004] Meanwhile, environmental factors during construction can also cause overturning accidents. For example, the construction space inside an inclined shaft is usually quite narrow, which restricts the movement of equipment and the operation of turn signals. If the operator operates improperly and the equipment collides with the shaft wall, it may cause the equipment to lose balance and overturn. In a narrow space, once the equipment tilts or other dangerous situations occur, it is difficult to have enough space to adjust and correct it.

[0005] Therefore, designing a system that can detect and warn when equipment shows signs of tipping over has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a trolley detection device and a trolley that can detect and warn when the equipment shows signs of tipping over.

[0007] The technical solution of this utility model is as follows:

[0008] A trolley detection device includes: a first limiting member disposed on the upper side of a track to limit the upward displacement of the track; two second limiting members located on both sides of the track to limit the lateral displacement of the track; and detection members disposed on both sides of the track in the upward direction and the lateral direction, for detecting the relative displacement between the first limiting member and the track, and between the second limiting member and the track, respectively.

[0009] Preferably, both the first limiting member and the second limiting member are rollers.

[0010] Preferably, the trolley detection device includes: a base, two bases respectively disposed on both sides of the track, and a first limiting member connecting the two bases.

[0011] Preferably, the base profile matches the track cross section to form a semi-enclosed structure.

[0012] Preferably, the two second limiting members are respectively disposed on the base.

[0013] Preferably, the trolley detection device includes: a housing for accommodating the base, the first limiting member and the second limiting member, wherein the second limiting member is connected to the housing.

[0014] Preferably, the detection element is mounted on the housing.

[0015] A trolley includes the aforementioned trolley detection device, which is fixedly installed on the trolley.

[0016] This application provides a trolley detection device and a trolley. The trolley detection device includes a first limiting member located on the upper side of the track to restrict the upward displacement of the track; two second limiting members located on both sides of the track to restrict the lateral displacement of the track; and detection members located on both sides in the upward and lateral directions of the track to detect the relative displacement between the first limiting member and the track, and between the second limiting members and the track, respectively. The core of this device lies in the multi-constraint mechanism to achieve the anti-tipping function. First, the first limiting member is located in the Z-axis direction (i.e., the upward direction of the track), controlling the track to rise. The two second limiting members constrain the lateral direction (X-direction), and the detection members monitor the relative displacement in each direction to form a closed-loop monitoring system. The first limiting member can also adopt the gravity self-locking principle; as long as the vertical pressure of the first limiting member is large enough, the track cannot disengage upwards. The dual-point arrangement of the second limiting members forms an anti-deflection moment. Simultaneously, detection members are set on three degrees of freedom, making the anti-tipping detection more reliable and accurate. Therefore, the trolley detection device and trolley provided in this application can detect and warn when the equipment shows signs of tipping over. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0022] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Figures 1 to 2 As shown, this utility model provides a trolley detection device, including: a first limiting member 1, which is disposed on the upper side of the track to limit the upward displacement of the track; a second limiting member 2, which is located on both sides of the track to limit the lateral displacement of the track; and detection members 3, which are provided on both sides of the track in the upward and lateral directions to detect the relative displacement between the first limiting member 1 and the track, and between the second limiting member 2 and the track, respectively.

[0024] The core of this device lies in its multiple constraint mechanisms to achieve anti-tipping functionality. Firstly, the first limiting component 1 is located upwards along the Z-axis (i.e., the upward direction of the track). The first limiting component 1 controls the track's upward movement. Two second limiting components 2 constrain the track laterally (in the X-direction). Then, detection components 3 monitor the relative displacement in each direction, forming a closed-loop monitoring system. The first limiting component 1 can also employ a gravity self-locking principle; as long as the vertical pressure of the first limiting component 1 is sufficient, the track cannot detach upwards. The dual-point arrangement of the second limiting components 2 creates an anti-deflection moment. Simultaneously, detection components 3 are placed in three degrees of freedom, making anti-tipping detection more reliable and accurate. Furthermore, the first limiting component 1, second limiting component 2, and detection components 3 are all modularly designed, facilitating maintenance.

[0025] In addition, the bottom surface of the first limiting member 1 that contacts the track can be made of a high-friction coefficient material, such as polyurethane coating, which can enhance the anti-lifting ability through the frictional self-locking effect. A buffer spring can also be installed inside the second limiting member 2 to allow slight track vibrations to reduce false alarms; rigid limiting will activate when the threshold is exceeded. Simultaneously, the detection component 3 can also adopt an embedded structure to directly measure the relative displacement between the first limiting member 1, the second limiting member 2, and the track contact surface, eliminating transmission errors. Therefore, the trolley detection device provided in this application can detect and warn when the equipment shows signs of tipping over.

[0026] In this design, both the first limiting component 1 and the second limiting component 2 are rollers. The core function of the roller design is the conversion between static and dynamic states. The roller of the first limiting component 1 must first address the vertical load transfer and displacement buffering. Ordinary limiting components cannot be simply applied. The first limiting component 1 is a roller structure, which can be configured to apply continuous downward pressure via a pre-tensioning spring or hydraulic cylinder. When the track is lifted by an external force, the roller converts the vertical displacement into its own rotational motion, simultaneously triggering the top detection component 3 to monitor the displacement increment. Meanwhile, the two second limiting components 2 on both sides are also roller structures. These two second limiting components 2 form a track clamping channel. When the track moves to the left, it compresses the left second limiting component 2, and the roller of the left second limiting component 2 triggers the left detection component 3. When the track moves to the right, it compresses the right second limiting component 2, and the roller of the right second limiting component 2 triggers the right detection component 3. All rollers can be fitted with high-precision tapered roller bearings to convert the sliding friction of the equipment into rolling friction, significantly reducing the coefficient of friction. In this embodiment, dynamic rolling friction is used to extend the life of the track. This roller-type limiting structure design not only ensures the safety of inclined shaft construction, but also achieves all-dimensional optimization of energy consumption, efficiency and maintenance costs. It is especially suitable for harsh working conditions with large inclination angles and high-frequency vibrations, upgrading traditional passive protection to active adaptive protection.

[0027] In the embodiments provided by this utility model, the trolley detection device includes: a base 4, with two bases 4 respectively disposed on both sides of the track, and a first limiting member 1 connecting the two bases 4. In this embodiment, by using two bases 4 and a cross-track connection spanning the two bases 4 with the first limiting member 1, this structure allows for a more balanced load distribution, avoids unilateral pressure on the track, and the two bases 4 can be independently leveled to adapt to irregular well bottoms. The modular design facilitates maintenance. This split base 4 reduces casting difficulty and lowers the manufacturing cost of the device. In addition, the first limiting member 1 acts as a connecting beam, converting the track load into pressure on both sides of the bases 4. This non-traditional cantilever beam structure avoids cracking caused by stress concentration.

[0028] Furthermore, the contour of base 4 matches the cross-section of the track, forming a semi-enclosed structure. Through the geometric matching of the inner contour of base 4 with the track cross-section, a C-shaped enclosed structure can be formed. The constraint mechanism in this embodiment is as follows: First, regarding vertical constraint, the track is lifted—the rollers are compressed—the pressure is transmitted through base 4; second, regarding lateral constraint, the track shifts laterally—the side rollers are squeezed—the detection element 3 detects the lateral displacement. When the track is subjected to eccentric loads, this semi-enclosed structure dissipates torsional energy through frictional damping of the inner cavity contact surface, suppressing track rotation.

[0029] In the embodiments provided by this utility model, two second limiting members 2 are respectively disposed on the base 4. This structure can adapt to the working condition where one side of the second limiting member 2 is damaged. In the trolley detection device provided by this application, when one side of the second limiting member 2 is damaged, the other side can still maintain 70% of the constraint force. This redundant design is crucial for life safety and has a better anti-fatigue fracture effect than the traditional single-point constraint under large tilt angle working conditions.

[0030] Furthermore, in the embodiments provided in this application, the trolley detection device includes: a housing 5, which accommodates the base 4, the first limiting member 1, and the second limiting member 2, with the second limiting member 2 connected to the housing 5. The sealed cavity in the structure of the housing 5 can withstand the high humidity environment of the inclined shaft, enabling the trolley detection device provided in this application to adapt to various extreme working conditions.

[0031] The detection element 3 is mounted on the housing 5. The detection element 3 can be a displacement or pressure sensor, which is fixed to the housing 5 by a high-rigidity connecting seat, forming an integral structure with the housing 5.

[0032] This application also provides a trolley, including the aforementioned trolley detection device, which also possesses all the technical advantages of the trolley detection device, and will not be described in detail here.

[0033] The embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other.
