Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a service elevator car. Background Technology

[0002] With the increasing demand for small-scale cargo transportation, dumbwaiters (mini or small elevators used in supermarkets, restaurants, warehouses, and other similar settings to transport goods, meals, and other items) are becoming increasingly common. These elevators typically rely on steel frame structures for fixed installation, and their structural stability directly affects the elevator's safety and lifespan.

[0003] Existing service elevator cars are generally welded together as a single unit, which is extremely inconvenient for transportation and handling. Furthermore, the load-bearing capacity of these welded cars is insufficient. In addition, these elevators used for transporting goods generally lack physical braking and locking mechanisms, relying solely on the power unit for stopping. When transporting heavy items to higher positions, and if electronic equipment malfunctions, there may be significant safety risks. Therefore, this utility model proposes a service elevator car to at least partially solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, this utility model proposes a service elevator car that overcomes or at least partially solves the above problems. It addresses the technical problems of existing service elevator cars with integrated welded structures, which are inconvenient to transport and handle, have insufficient load-bearing capacity, and lack a physical braking and locking structure, leading to significant safety risks.

[0005] To address the aforementioned problems, this utility model discloses a service elevator car, comprising:

[0006] A first plate is arranged in parallel, with a first right-angled folded edge on both sides; the first right-angled folded edge is connected to the side of a second plate by screws, and the second plate has a second right-angled folded edge at its upper and lower ends; the second right-angled folded edge has multiple screw holes and / or waist holes; a base plate is connected to the second right-angled folded edge by screws; both the first and second plates are provided with a reinforcing frame structure; at least one of the first plates is provided with a locking pin assembly; the locking pin assembly is located near the edge of the second plate.

[0007] Furthermore, the locking pin assembly includes a pin holder mounted on the first plate, a pin rod inserted laterally on the pin holder, and a push handle connected to the pin rod.

[0008] Furthermore, the end of the push handle is spherical.

[0009] Furthermore, it also includes a protective cover; the protective cover is installed on the first plate or the reinforcing frame structure and sleeved on the outside of the locking pin assembly; the upper end of the protective cover is provided with a U-shaped hole, and the push handle extends out of the outside of the U-shaped hole.

[0010] Furthermore, it also includes a side guard plate, which is connected to the second plate and covers the side end of the protective cover; the protective cover has a through hole, and the end of the pin passes through the through hole.

[0011] Furthermore, the reinforcing frame structure includes a reinforcing frame mounted on the first plate and at least one crossbar mounted on the second plate; both ends of the crossbar are connected to the reinforcing frame.

[0012] The embodiments of this utility model have the following advantages:

[0013] By adopting a detachable structure with screws connecting the first plate, the second plate, and the base plate, the traditional one-piece welded structure is replaced. During transportation and handling, each plate can be transported separately, which greatly reduces the transportation volume, reduces transportation difficulty and cost, and also facilitates on-site handling and installation operations.

[0014] The reinforced frame structure effectively improves the structural strength and stability of the first and second plates, thereby enhancing the load-bearing capacity of the entire car. This makes the car less prone to deformation and shaking when transporting heavy items, ensuring the normal operation of the elevator and extending the service life of the car.

[0015] The locking pin assembly provides a physical braking and locking function for the car. When the car is stationary, especially when transporting heavy items to a higher position, even if the electronic equipment fails and the power unit fails to stop, the locking pin assembly can physically lock the car to the supporting steel frame, effectively preventing the car from falling and significantly improving the safety of the dumbwaiter.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 2 As shown in some embodiments of this utility model, a service elevator car includes: a first plate 1 arranged in parallel, with a first right-angled folded edge 11 on both sides of the first plate 1; the first right-angled folded edge 11 is connected to the side of a second plate 2 by screws, and the second plate 2 has a second right-angled folded edge 21 at its upper and lower ends; the second right-angled folded edge 21 has a plurality of screw holes and / or waist holes; a base plate is connected to the second right-angled folded edge 21 by screws; both the first plate 1 and the second plate 2 are provided with a reinforcing frame structure; at least one of the first plates 1 is provided with a locking pin assembly; the locking pin assembly is located near the edge of the second plate 2.

[0023] The aforementioned detachable connection structure, comprising a first plate 1, a second plate 2, and a base plate connected by screws, replaces the traditional one-piece welding. It can be disassembled for transportation, reducing transport volume, difficulty, and cost, while facilitating on-site handling and installation. The reinforcing frame structure on the first plate 1 and second plate 2 enhances the structural strength and stability of the plates, thereby improving the overall load-bearing capacity of the car and preventing deformation and swaying when transporting heavy objects. The locking pin assembly provides a physical braking and locking function, preventing the car from falling due to electronic equipment failure or power braking failure, ensuring the safety of personnel and goods. For example, a logistics warehouse needs to install a dumbwaiter using the car structure claimed in this claim. During transportation, the first plate, second plate, base plate, and reinforcing frame structure are disassembled and transported by ordinary trucks. Compared to a traditional one-piece welded car, transportation costs are reduced by 40%, and the components can be easily moved and installed in the narrow aisles of the warehouse. In daily use, the car can stably carry 800kg of goods, while traditional one-piece welded cars will deform slightly when carrying 600kg. When transporting 700kg of goods to a height of 10 floors, the electronic equipment suddenly malfunctioned. The operator used the locking pin assembly to lock the car to the supporting steel frame, preventing the car from falling.

[0024] Furthermore, the locking pin assembly includes a pin holder 5 mounted on the first plate 1, a pin rod 6 horizontally inserted into the pin holder 5, and a push handle 7 connected to the pin rod 6. Figure 1As shown, the pin bracket 5 can be configured as a U-shape, with the pin rod 6 passing through both side walls of the U-shaped pin bracket 5. The push handle 7 is connected to the pin rod 6 located between the two side walls of the U-shaped pin bracket 5. The pin bracket 5 provides stable installation support for the pin rod 6, ensuring smooth lateral movement of the pin rod 6. The push handle 7 allows operators to easily control the extension and retraction of the pin rod, enabling quick locking and unlocking of the car and the supporting steel frame, making operation convenient and efficient. For example, during the maintenance of a supermarket dumbwaiter, when the car needs to be stopped at a specific floor for repair, maintenance personnel can easily insert the pin rod 6 into the socket of the supporting steel frame by pushing the push handle 7 on the pin rod 6, completing the locking of the car. The entire operation takes only a few seconds. After the repair is completed, pushing the handle 7 in the opposite direction will pull out the pin rod and unlock it, greatly improving the efficiency of the repair work.

[0025] It should be noted that, since the aforementioned pin 6 can connect with the corresponding socket on the supporting steel frame when locked, it ensures that the elevator car can be physically locked when it is stationary, preventing it from falling due to failure of the power components. Because the support structure scheme is a different technical solution from this application, its structure will not be described in detail here; only the holes or other supporting structures accessible when the pin extends outwards from the support structure will be described.

[0026] Furthermore, the end of the push handle 7 is spherical. The spherical end of the push handle 7 improves operator comfort and prevents sharp edges from scratching hands. Simultaneously, the spherical structure provides a certain degree of slip resistance, facilitating force application and ensuring stable operation, especially when hands are slightly oily or damp. For example, in food processing plants, operators' hands may be slightly contaminated with cooking oil due to environmental conditions. When the locking pin assembly needs to be operated to lock the car, the spherical end of the push handle 7 is less prone to slipping, allowing operators to easily push the handle 7 to complete the locking operation without scratching their hands, thus ensuring operator safety and comfort.

[0027] In some embodiments of this application, a protective cover 8 is also included; the protective cover 8 is installed on the first plate 1 or the reinforcing frame structure and is fitted over the outside of the locking pin assembly; the upper end of the protective cover 8 is provided with a U-shaped hole 81, and the push handle 7 extends out of the outside of the U-shaped hole 81. The protective cover 8, fitted over the outside of the locking pin assembly, can effectively prevent dust and debris from entering the interior of the locking pin assembly, preventing them from affecting the sliding of the pin rod and ensuring the long-term stable operation of the locking pin assembly; the U-shaped hole 81 not only does not affect the normal operation of the push handle 7, but also limits the range of movement of the push handle 7 to a certain extent, avoiding damage to the locking pin assembly due to excessive movement of the handle.

[0028] Furthermore, it also includes a side guard plate 82, which is connected to the second plate 2 and covers the side end of the protective cover 8; the protective cover 8 has a through hole through which the end of the pin 6 protrudes. The aforementioned side guard plate cover 82 is located on the side end of the protective cover 8, further strengthening the protection of the locking pin assembly and preventing dust and debris entering from the side of the car from affecting the locking pin assembly; the through hole on the protective cover 8 ensures that the end of the pin can smoothly pass through and insert into the support steel frame insertion hole without affecting the locking function of the locking pin assembly, while making the internal structure of the car more regular. For example, in the application scenario of a machinery factory, in its service elevator, some small parts are sometimes piled up on the side of the car. The side guard plate 82 can prevent these parts from accidentally falling into the gap between the protective cover 8 and the second plate 2, and then entering the interior of the locking pin assembly.

[0029] The reinforcing frame structure includes a reinforcing frame 3 installed on the first plate 1 and at least one crossbar 4 installed on the second plate 2; both ends of the crossbar 4 are connected to the reinforcing frame 3. The reinforcing frame 3 effectively enhances the deformation resistance of the first plate 1. The crossbar 4 connects to the reinforcing frame 3, forming an integral reinforced structure. This not only enhances the strength of the second plate 2 but also improves the connection stability between the first plate 1 and the second plate 2, further enhancing the load-bearing capacity and structural stability of the entire car. Figure 1 and Figure 2 Preferably, two rods are provided on the second plate 2 on each side.

[0030] For example, this embodiment provides a service elevator car, such as Figure 1 and Figure 2 As shown, the assembly includes two parallel first plates 1, positioned opposite each other. Each first plate 1 has a first right-angled folded edge 11 integrally formed on both sides, with screw holes on the first right-angled folded edge 11. Two second plates 2 are provided, located on either side of the two first plates 1. The sides of the second plates 2 are fastened to the first right-angled folded edges 11 with screws, thus assembling the first plates 1 and the second plates 2. The upper and lower ends of the second plates 2 also have second right-angled folded edges 21 integrally formed. The second right-angled folded edges 21 have multiple screw holes and slotted holes. The screw holes are used for fixing, while the slotted holes facilitate fine-tuning during installation, improving ease of installation. The base plate (not shown) is made of metal, and its edge is connected to the second right-angled folded edges 21 with screws. The screws pass through pre-drilled holes on the base plate and engage with the screw holes or slotted holes on the second right-angled folded edges 21 to fix the base plate to the second plates 2, thereby forming a chamber for accommodating items.

[0031] Both the first plate 1 and the second plate 2 are equipped with reinforcing frame structures. These structures include a reinforcing frame 3 installed inside the first plate 1, which is welded from square steel and fixed to the inner wall of the first plate 1 with screws. This effectively enhances the deformation resistance of the first plate 1. Two crossbars 4, made of stainless steel, are installed inside the second plate 2. The ends of the crossbars 4 are fixed to the reinforcing frame 3 with screws, forming a unified reinforced structure. This further improves the overall structural strength and load-bearing capacity of the car. Testing shows that this structure increases the load-bearing capacity of the car by more than 30% compared to traditional one-piece welded cars.

[0032] A locking pin assembly is provided on one of the first plate members 1 near the edge of the second plate member 2. The locking pin assembly includes a pin frame 5 installed on the inner side of the first plate member 1. The pin frame 5 is U-shaped and made of bent steel plate, then fixed to the first plate member 1 with screws. A pin rod 6 is inserted laterally into the pin frame 5. The pin rod 6 can slide between the two side walls of the pin frame 5. A push handle 7 is welded to the pin rod 6 between the two side walls of the U-shaped pin frame 5. Pushing the handle 7 can drive the pin rod 6 to move laterally. When the car needs to be locked, push the push handle 7 to insert the end of the pin rod 6 into the corresponding socket set on the supporting steel frame, realizing the physical locking of the car; when it is necessary to unlock, push the push handle 7 in the opposite direction to pull the pin rod 6 out of the socket in the supporting steel frame.

[0033] Furthermore, based on the above, the push handle 7 has been optimized by making its end spherical. This design makes the operator feel more comfortable when pushing the handle, avoiding the possibility of the handle end being sharp and scratching the hand; on the other hand, the spherical end can also play a role in preventing slippage, making it easier for the operator to apply force.

[0034] Furthermore, based on the above, a protective cover 8 is added. The protective cover 8 is made of plastic and is screwed onto the inner wall of the first plate 1, fitting over the outside of the locking pin assembly. A U-shaped hole 81 is provided at the upper end of the protective cover 8, through which the push handle 7 extends outwards for easy operation. The protective cover 8 effectively prevents dust and debris from entering the locking pin assembly and affecting the sliding performance of the pin 6, ensuring the normal operation of the locking pin assembly. It also prevents accidental contact with the locking pin assembly.

[0035] Furthermore, based on the above, a side guard plate 82 is added. The side guard plate 82 is made of thin metal sheet and is connected to the inner wall of the second plate 2 by screws, covering the side end of the protective cover 8. A through hole is provided on the side of the protective cover 8 near the side guard plate 82. The end of the pin 6 passes through this through hole and is then inserted into the insertion hole of the supporting steel frame. The side guard plate 82 further protects the locking pin assembly, preventing dust and debris entering from the side of the car from affecting its operation, and also makes the internal structure of the car more regular and aesthetically pleasing.

[0036] In this application, the base plate is preferably made of Q235 steel plate with a thickness of 5-8mm. Its dimensions match the bottom opening size formed after the first plate 1 and the second plate 2 are assembled. That is, the length of the base plate is the same as the length of the first plate 1, and the width is slightly larger than the distance between the two second plates 2. The number of pre-drilled holes on the base plate is equal to the total number of screw holes and waist holes on the second right-angle folded edge 21, and their positions correspond one-to-one. The diameter of the pre-drilled holes is 0.5-1mm larger than the nominal diameter of the connecting screws so that the screws can pass through smoothly. The reinforcing frame is made of rectangular square steel with a cross-sectional dimension of 30mm×30mm-50mm×50mm. The shape of the reinforcing frame is adapted to the shape of the first plate 1. That is, the reinforcing frame is a rectangular frame of the same size as the first plate 1. The four sides of the frame are fixedly connected to the inner sidewall of the first plate by M8-M12 screws. The screw spacing is 150-200mm to ensure that the reinforcing frame is firmly connected to the first plate. The aforementioned crossbars are made of stainless steel round or flat bars. If round, the diameter is 10-16mm; if flat, the cross-sectional dimensions are 20mm×3mm-30mm×5mm. The number of crossbars can be determined based on the height of the second plate, generally 2-4 bars are provided, evenly distributed on the outer wall of the second plate 2. The crossbars 4 are fixed to the second plate 2 by welding or screws; both ends of the crossbars 4 are connected to the reinforcing frame 3 by screws, for example, M6-M10 screws, ensuring a stable connection between the crossbars 3 and the reinforcing frame 4.

[0037] The pin bracket 5 and the first plate 1 can be fixedly connected by M6-M8 screws or directly welded. There should be at least two screws, symmetrically distributed on both sides of the pin bracket to ensure a secure installation. The pin rod 6 is made of 45# steel with a diameter of 12-18mm. The length of the pin rod 6 should ensure that when fully extended, its end can be inserted into the insertion hole of the supporting steel frame to a depth of not less than 20mm. The diameter of the insertion hole on the supporting steel frame is 0.2-0.5mm larger than the diameter of the pin rod, and the position of the insertion hole should be aligned with the locking pin assembly.
