Description

Technical Field

[0001] This utility model relates to the field of building road construction technology, specifically a portable multi-functional T-shaped bend. Background Technology

[0002] Faced with the current situation of a super-large operating network, a surge in the number of vehicles, extended operating hours, and increased maintenance pressure, coupled with the long construction period, the continuous opening of new lines, and the fact that old lines have entered a phase of large-scale equipment updates and renovations, and the long-term pressure of high-load operation, higher requirements are placed on the safety and quality of current equipment maintenance work.

[0003] The fastening system is an important component of track maintenance equipment, ensuring the geometric dimensions and stability of the track, and guaranteeing the smoothness and safety of subway operation. As the service time of the fastening bolts goes by, loosening, corrosion, and decreased fastening force will inevitably occur. Therefore, the disassembly, inspection, re-tightening, and torque measurement of fasteners are particularly important.

[0004] During maintenance work, due to the large number and variety of bolt types, a large number of tools and equipment need to be carried, making construction inconvenient and costly. Similar tools, such as single-type T-shaped benders and fastener tightening robots, are available in daily operations both domestically and internationally. However, these tools are not convenient for quickly changing socket heads. Furthermore, due to factors such as extended operation during subway nighttime maintenance windows, the effective construction time is short. Some tools are heavy and have many parts, and a single operation generally requires 2 to 3 people. This makes it inconvenient for routine inspections and disassembly and maintenance of rusted areas, resulting in poor portability. Summary of the Invention

[0005] The purpose of this utility model is to provide a portable multifunctional T-shaped crutch, which aims to effectively solve the problem of insufficient portability and ease of use of existing similar components.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A portable multi-functional T-shaped lever includes a display screen, a force-applying handle, and a connecting post. A sleeve is fixedly installed at the end of the force-applying handle away from the display screen. A slot is provided at the end of the sleeve away from the force-applying handle. A force-applying handle assembly is inserted into the sleeve through the slot. A connecting cylinder is fixedly installed at the end of the connecting post away from the display screen. A replacement sleeve is threadedly connected to the outer edge of the connecting cylinder away from the connecting cylinder. A sleeve is threadedly connected to the end of the replacement sleeve away from the first connecting block.

[0008] Preferably, the force-applying handle assembly includes an extended handle, and a locking element and a locking block are fixedly installed at one end of the extended handle near the force-applying handle. The locking element near the force-applying handle has an inclined design, and the locking element and the locking block are elastic locking elements.

[0009] Preferably, the end of the sleeve near the force-applying handle has a slot, the extended handle and the slot are plugged in, and the slot is engaged with the card block.

[0010] Through the above technical solution, the slot of the insert and the block of the force-extending handle assembly form an elastic locking structure. The inclined design of the clip can slide into the slot when inserted, and the installation and removal of the extended handle can be completed without tools. This makes it easy to adjust the handle length according to actual conditions, and it can also be removed when carrying, which can improve its portability.

[0011] Preferably, the extended handle has anti-slip texture at the outer edge away from the insert, and two identical force-applying handles, inserts, and force-applying handle assemblies are provided, with the two force-applying handles, inserts, and force-applying handle assemblies symmetrically distributed about the center line of the display screen.

[0012] The above technical solution increases the friction when gripping by extending the anti-slip texture of the handle, avoiding slippage caused by sweaty hands. Furthermore, the design of the two force-applying handles, the sleeve, and the force-adding handle assembly allows the torque reaction force to be counteracted by the coordinated force exerted by both hands.

[0013] Preferably, the display screen is equipped with a battery, and a torque sensor is fixedly installed at the end of the display screen away from the force application handle and close to the connecting post. The torque sensor is connected to the connecting post, and the torque sensor model is AKC-17C-3000Nm.

[0014] The above technical solution uses an AKC-17C-3000Nm torque sensor to collect real-time tightening torque data of fastener bolts, and the display screen simultaneously displays the values ​​and stores historical data.

[0015] Preferably, a first connecting block is fixedly installed at the end of the connecting cylinder away from the connecting post. The first connecting block is threadedly connected to the replacement sleeve, and the length of the first connecting block is half the length of the replacement sleeve.

[0016] Through the above technical solution, the first connecting block of the connecting sleeve and the replacement sleeve are threaded together with a length ratio of 1:2. The extension length of the sleeve can be adjusted by rotating the replacement sleeve. The second connecting block is fixedly installed at one end near the connecting column. The inner edge of the sleeve is provided with connecting grooves, and the second connecting block and the connecting grooves are threaded together.

[0017] With the above technical solution, through the cooperation of the second connecting block and the connecting thread, before installing the replacement sleeve, the sleeve can be connected to the replacement sleeve first, and then the sleeve can be put into the other end of the replacement sleeve. At the same time, the first connecting block and the sleeve can be aligned first, and then the replacement sleeve can be rotated to lock. Different replacement methods can be selected according to the actual situation, thereby realizing quick replacement of the sleeve.

[0018] Preferably, the sleeve has a threaded hole at the end away from the connecting post, and the threaded hole has a "regular hexagonal" cross-section.

[0019] Through the above technical solution, by designing the sleeve and screw hole, after adjusting the appropriate sleeve, the screw hole can be aligned with the test bolt. Then, by rotating the force-applying handle assembly and cooperating with the torque sensor, the test can be achieved.

[0020] Compared with the prior art, the portable multifunctional T-shaped crutch provided by this utility model has the following beneficial effects:

[0021] 1. This portable multi-functional T-shaped bend, through the cooperation of the second connecting block and the connecting thread, can realize the design of the sleeve before installation and replacement, and can also lock the sleeve and the replacement sleeve together after alignment, thereby achieving a locking between the two. The sleeve can be quickly replaced according to the actual situation, which can effectively improve the construction efficiency.

[0022] 2. This portable multi-functional T-shaped crutch uses a slot in the insert and a block in the force-extending handle assembly to form an elastic locking structure. The inclined design of the clip allows it to slide into the slot when inserted, enabling the installation and removal of the extended handle without tools. This facilitates adjusting the handle length according to actual needs and also allows it to be removed when carrying, thus improving its portability. Attached Figure Description

[0033] 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.

[0034] Example 1:

[0035] like Figure 1-3 As shown in the figure, this example provides a portable multi-functional T-shaped lever, including a display screen 1, a force-applying handle 2, and a connecting post 9. A sleeve 3 is fixedly installed at the end of the force-applying handle 2 away from the display screen 1. A slot 4 is opened at the end of the sleeve 3 away from the force-applying handle 2. A force-applying handle assembly 6 is installed by inserting the sleeve 3 through the slot 4. A connecting cylinder 10 is fixedly installed at the end of the connecting post 9 away from the display screen 1. A replacement sleeve 15 is threadedly connected at the outer edge of the connecting cylinder 10 away from the connecting cylinder 10. A sleeve 12 is threadedly connected at the end of the replacement sleeve 15 away from the first connecting block 11.

[0036] See further Figure 4 and Figure 5 The force-applying handle assembly 6 in this portable multi-functional T-shaped crutch includes an extended handle 601. A locking piece 603 and a locking block 604 are fixedly installed on one end of the extended handle 601 near the force-applying handle 2. The end of the locking piece 603 near the force-applying handle 2 is designed with an inclination. The locking piece 603 and the locking block 604 are elastic locking pieces.

[0037] Furthermore, in this example, a slot 5 is provided at the end of the sleeve 3 near the force-applying handle 2. The extended handle 601 is inserted into the slot 4, and the slot 5 is engaged with the locking block 604. With this configuration, the slot 5 of the sleeve 3 and the locking block 604 of the force-applying handle assembly 6 form an elastic locking structure. The inclined locking piece 603 can slide into the slot 5 during insertion, allowing the extended handle 601 to be installed and removed without tools. This facilitates adjustment of the handle length according to actual needs and also allows it to be removed for carrying, improving its portability.

[0038] Furthermore, in this example, the extended handle 601 has anti-slip texture 602 at the outer edge away from the sleeve 3. The force-applying handle 2, sleeve 3 and force-applying handle assembly 6 are provided in two identical parts, and the two force-applying handles 2, sleeve 3 and force-applying handle assembly 6 are symmetrically distributed about the center line of the display screen 1.

[0039] This design increases the friction when gripping by extending the anti-slip texture 602 of the handle 601, preventing slippage caused by sweaty hands. Furthermore, the design of the two force-applying handles 2, the insert 3, and the force-adding handle assembly 6 allows the torque reaction force to be counteracted by the coordinated force exerted by both hands.

[0040] Further integration Figure 1-3 as well as Figure 6 As shown, in this example, a battery 7 is installed inside the display screen 1. At the same time, a torque sensor 8 is fixedly installed at the end of the display screen 1 away from the force application handle 2 and close to the connecting post 9. The torque sensor 8 is connected to the connecting post 9. Here, the torque sensor 8 is preferably an AKC-17C-3000Nm torque sensor.

[0041] With this setup, the torque sensor 8, model AKC-17C-3000Nm, can collect the tightening torque data of the fastener bolts in real time, and the display screen 1 can simultaneously display the values ​​and store historical data.

[0042] Example 2:

[0043] This example further modifies the solution in Embodiment 1 to provide an improved solution.

[0044] Further integration Figures 7 to 9 As shown, this example, based on the solution in Example 1, further improves upon...

[0045] A first connecting block 11 is fixedly installed at the end of the connecting cylinder 10 away from the connecting post 9. The first connecting block 11 is threadedly connected to the replacement sleeve 15, and the length of the first connecting block 11 is half the length of the replacement sleeve 15.

[0046] With this configuration, the first connecting block 11 of the connecting sleeve 10 and the replacement sleeve 15 are threaded together with a length ratio of 1:2. Rotating the replacement sleeve 15 can adjust the extension length of the sleeve 12 to accommodate fastener bolts of different depths.

[0047] Furthermore, in this example, a second connecting block 13 is fixedly installed at one end of the sleeve 12 near the connecting post 9. A connecting thread 16 is provided on the inner edge of the sleeve 12, and the second connecting block 13 and the connecting thread 16 are connected by a thread.

[0048] With this configuration, through the cooperation of the second connecting block 13 and the connecting thread 16, before installing the replacement sleeve 15, the sleeve 12 can be threadedly connected to the replacement sleeve 15, and then the sleeve 12 can be fitted onto the other end of the replacement sleeve 15 and locked. Alternatively, the first connecting block 11 can be aligned with the sleeve 12 first, and then the replacement sleeve 15 can be rotated and locked. Different installation methods can be selected according to the actual situation, thereby achieving quick replacement of the sleeve 12.

[0049] Furthermore, in this example, a screw hole 14 is provided at the end of the sleeve 12 away from the connecting post 9, and the cross-section of the screw hole 14 is a regular hexagonal structure.

[0050] With this setup, by adjusting the sleeve 12 and screw hole 14 to a suitable position, the screw hole 14 can be aligned with the test bolt. Then, by rotating the force-applying handle assembly 6 and engaging the torque sensor 8, the test can be performed.

[0051] The following is a detailed explanation of the operation process of the portable multi-functional T-shaped crutch developed in the above example.

[0052] Combination Figures 1 to 9 As shown, when this portable multi-functional T-shaped crutch is in use, the slot 5 of the insert 3 and the locking block 604 of the force-extending handle assembly 6 form an elastic locking structure. The inclined design of the locking piece 603 can slide into the slot 5 when inserted, and the extension handle 601 can be installed and removed without tools. This makes it easy to adjust the handle length according to the actual situation, and it can also be removed when carrying, which can improve its portability.

[0053] Furthermore, the anti-slip texture 602 of the extended handle 601 increases the friction when gripping, preventing slippage caused by sweaty hands. The design of the two force-applying handles 2, the sleeve 3, and the force-adding handle assembly 6 allows the torque reaction force to be counteracted by the coordinated force of both hands.

[0054] The first connecting block 11 of the connecting sleeve 10 is threaded with the replacement sleeve 15 with a 1:2 length ratio. Rotating the replacement sleeve 15 can adjust the extension length of the sleeve 12 to accommodate fastener bolts of different depths. Through the cooperation of the second connecting block 13 and the connecting thread 16, before installing the replacement sleeve 15, the sleeve 12 can be threadedly connected to the replacement sleeve 15 first, and then the sleeve 12 can be inserted into the other end of the replacement sleeve 15 and locked. Alternatively, the first connecting block 11 and the sleeve 12 can be aligned first, and then the replacement sleeve 15 can be rotated and locked. Different installation methods can be selected according to the actual situation to achieve quick replacement of the sleeve 12. Through the design of the sleeve 12 and the screw hole 14, after adjusting the sleeve 12 appropriately, the screw hole 14 can be aligned with the test bolt for operation.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
