Description

Technical Field

[0001] The present invention relates to the technical field of freight lifts, and in particular to a hydraulic guide rail type freight lift. Background Art

[0002] The hydraulic rail freight elevator is a device used for vertical lifting of materials. It mainly uses the hydraulic system to drive the lifting platform to move vertically in the guide rail. Its working principle is relatively simple. It can efficiently and safely transport items from one floor to another without the need for a pit or a machine room. It is particularly suitable for workplaces such as basements, warehouse renovations, and new shelves where pits cannot be excavated. It is widely used in warehouses, factories, logistics centers and other places.

[0003] During use, external goods are usually pushed into the freight elevator through roller carts. Due to the lack of limiting equipment for the carts in the freight elevator, the cargo carts are prone to move during the lifting process, which in turn causes the freight elevator to be overweight, resulting in an unbalanced load during transportation, thereby affecting the operational stability of the freight elevator. In order to ensure the stability of the freight elevator during operation, it is necessary to prevent the goods from moving. The existing solution relies on manually wrapping and binding the carts with ropes and fixing the goods through the buckle position.

[0004] However, there are several problems with this fixing method: first, the manual bundling process is cumbersome and time-consuming, and requires wrapping around the buckles one by one, which increases the complexity of manual operation and reduces work efficiency; second, when the goods are transported and arrive at the designated location, the ropes need to be manually untied one by one, further increasing the operation time and labor intensity. This process not only consumes a lot of time, but also easily leads to the goods being not firmly fixed due to improper operation, increasing safety risks.

[0005] In addition, the existing bundling and limiting methods are relatively simple. When the freight elevator carries multiple goods, the bundling effect of the rope alone is often not enough to ensure that all the goods can be stably fixed. The goods may collide, shake, or even fall. Especially when transporting a large number of goods or heavy goods, the bundling fixing effect is insufficient and they are prone to movement. Summary of the invention

[0006] The present invention provides a hydraulic guide rail freight elevator, which solves the problem that the existing freight elevator has a time-consuming and cumbersome manual bundling method for fixing the transported goods, and the goods need to be wrapped one by one with buckles, which is complicated to operate and inefficient. After the transportation is completed, manual untying is required, which increases the operation time and labor intensity, and may lead to loose fixation due to improper operation, posing a safety hazard. In addition, the bundling and limiting method is single, and the stability of multiple pieces of goods or heavy goods is insufficient, which can easily cause the goods to collide, shake or even fall, and the fixing effect is difficult to meet the technical problems of multiple cargo transportation needs.

[0007] The present invention provides a hydraulic guide rail type lifting freight elevator, comprising a guide rail frame, a car body slidably connected to the guide rail frame, a hydraulic lifting rod fixedly connected between the guide rail frame and the car body, and two car doors symmetrically slidably installed on the front of the car body. A quick-tying part for quickly tying up the goods put into the car body and flexibly adjusting the tying range according to the width of the goods is arranged on the car body car floor. The quick-tying part comprises a plurality of winding mechanisms equidistantly arranged on the left part of the car body car floor and a plurality of piercing rings equidistantly arranged on the right part of the car body cavity bottom. The winding mechanism is used to combine with the piercing ring to quickly tie up and limit the goods put into the car body. A synchronous untying mechanism is jointly arranged on the car floor of the main body and between the winding mechanism, and is used to link with the winding mechanism so as to synchronously and quickly untie the bundled goods.

[0010] In a possible implementation, the ring-threading member includes a mounting block that is embedded and fixedly connected to the bottom of the car body cavity, and a rope-threading ring that is hinged to the middle part of the upper end surface of the mounting block through a lug.

[0011] In a possible implementation, two C-shaped grooves are symmetrically provided on the front and rear ends of the upper end surface of the mounting block for facilitating the insertion and placement of the rope threading ring, and the proximal ends of the two C-shaped grooves are connected to each other.

[0012] In one possible implementation, the top limit mechanism includes a connecting rod, a side push rod, an L-shaped groove, an L-shaped lever and a strip frame. Rectangular grooves are provided at the lower portions of the left and right cavity walls of the car body. The upper groove wall of the rectangular groove is symmetrically hinged with a connecting rod through a protrusion. The lower ends of the front and rear connecting rods are commonly fixedly connected to a side push rod. Two L-shaped grooves with upper openings are symmetrically provided at the front of the car bottom of the car body. A strip through groove is provided on the front groove wall of the L-shaped groove. An L-shaped lever for cooperating with the car door is slidably connected between the L-shaped groove and the strip through groove. The long sections of the two L-shaped levers are fixedly connected to a strip frame slidably arranged in the vertical section of the L-shaped groove on the opposite sides, and the strip frame is slidably sleeved on the outside of the side push rod.

[0016] In one possible implementation, a docking block is fixedly connected to the end of the telescopic section of the telescopic rod, a docking column is fixedly connected to the left side of the docking block away from the telescopic rod, and a docking groove that cooperates with the docking column is provided on the left side of the docking block away from the telescopic rod.

[0017] It can be seen from the above technical solutions that the present invention has the following advantages:

[0018] In the present invention, through the combination of the winding mechanism and the ring-piercing piece, a single tying rope can be used to complete the overall bundling of the goods. At the same time, when untying, it is only necessary to control the plug tongue to disengage from the plug hole, and use the reel to quickly wind up the tying rope. The manual bundling and untying process is greatly simplified, reducing the complicated operation of checking the buckles one by one, improving work efficiency, and the simplified fixing and untying method reduces the chance of human operational errors, ensuring that the goods are stable and do not shake during transportation, reducing the risk of goods falling or being damaged, and improving the safety of freight elevator operation.

[0019] In the present invention, through the combination of the cylinder sleeve, the sliding column seat, the telescopic rod and the notch groove in the blocking mechanism, the spacing of the telescopic rods can be flexibly adjusted according to the front and rear width of the goods, so that the corresponding telescopic rods on the left and right sides are in contact with the side positions of the goods, thereby achieving the front and rear and side positioning of the goods, ensuring that the goods do not shift during transportation, and at the same time facilitating the neat arrangement of the goods into the freight elevator, thereby improving the operating stability of the freight elevator.

[0020] In the present invention, the upper limit mechanism is linked with the closing elevator door to touch the left and right sides of the cargo, ensuring that the cargo always maintains a stable position inside the cargo elevator. At the same time, the binding ropes in the upper and lower quick-binding parts are tightened again to provide additional fixing force, making it difficult for the cargo to shake or shift during transportation, thereby greatly enhancing the stability of the cargo and further enhancing the safety of cargo operation.

[0021] In the present invention, the goods in the freight elevator are limited from multiple different directions by combining the quick-tying part, the blocking mechanism and the top limit mechanism. The multi-directional restrictions ensure that the goods will not be offset, shaken or tilted in any form in the freight elevator, providing a more comprehensive and firmer fixing effect, avoiding the problem of unbalanced weight of the freight elevator during operation, and greatly improving the operating stability and safety of the freight elevator.

The two blocking limit mechanisms 8 are used to combine with each other to block and limit the goods placed in the car from the front and rear sides. The quick bundling part, the top limit mechanism 7 and the blocking limit mechanism 8 are combined with each other to limit the goods placed in the car body 2 from different directions for multiple times, thereby ensuring the stability of the car body 2 during operation.

[0039] See also Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.11The reel 43 is connected to the mounting groove 42 by a rotating shaft, and a torsion spring is fixedly connected to the mounting groove 42. A binding rope 44 is wound around the outside of the reel 43, and an arrow-shaped tongue 45 is fixedly connected to the end of the binding rope 44 away from the reel 43. A socket 46 for cooperating with the tongue 45 is provided at the rear end of the upper end surface of the mounting seat 41, and a slot 47 is provided on the outside of the tongue 45. A transverse groove communicating with the socket 46 is provided inside the mounting seat 41, and a clamping strip 48 for cooperating with the slot 47 is slidably connected in the transverse groove. A locking component 49 for cooperating with the tongue 45 to lock the reel 43 is provided in the mounting seat 41, and a conical guide sleeve arranged on the outside of the binding rope 44 is fixedly connected to the lower end surface of the tongue 45.

[0040] See also Figure 8 and Fig. 9 The locking assembly 49 includes a plug column 491 and a column hole 492. A columnar groove is opened in the installation groove 42 for connecting the installation groove 42 and the insertion hole 46. The plug column 491 is slidably connected in the columnar groove. The rear end of the plug column 491 extends into the insertion hole 46. A limit spring is fixedly connected between the plug column 491 and the columnar groove. A plurality of column holes 492 for cooperating with the plug column 491 are equidistantly opened on one side of the reel 43 close to the insertion hole 46. The middle section of the plug column 491 is a spring expansion section.

[0041] See also Figure 3 and Figure 4 The ring-threading member 5 includes a mounting block 51 which is embedded and fixedly connected to the bottom of the car body 2, and a rope-threading ring 52 which is hinged to the middle part of the upper end surface of the mounting block 51 through a lug. The upper end surface of the mounting block 51 is symmetrically provided with two C-shaped grooves 10 which are convenient for the rope-threading ring 52 to be embedded and placed, and the proximal ends of the two C-shaped grooves 10 are connected to each other. The C-shaped grooves 10 are used to make the rope-threading ring 52 embedded in the C-shaped grooves 10 in the initial state, ensuring that the bottom of the car body 2 is in a flat state, preventing the erected rope-threading ring 52 from blocking the cargo cart moving into the car body 2.

[0042] See also Figure 5 , Fig.10 and Fig.11 The synchronous release mechanism 6 includes a cylindrical groove 61 which is jointly opened between the car body 2 and the mounting seat 41 and connected to the left part of the transverse groove. A column rod 63 is slidably connected in the cylindrical groove 61. A top spring 62 is fixedly connected between the column rod 63 and the cylindrical groove 61. The clamping strip 48 is fixedly connected to the outer wall of the column rod 63. A strip groove connected to the cylindrical groove 61 is opened at the front part of the bottom of the car body 2. A push plate 9 slidably set in the strip groove is fixedly connected to the outside of the column rod 63.

[0043] The carts loaded with goods (hereinafter referred to as goods) are pushed into the freight elevator in sequence and placed in the middle of the freight elevator to prevent the freight elevator from being overweight. When the first goods pushed into the freight elevator are moved to the rear of the freight elevator, the operator manually pulls the tongue 45 to move (the tongue 45 is initially retracted in the installation slot 42), and the tongue 45 then drives the rope 44 to move and extend the rope 44, which then drives the drum 43 to rotate, and the rope 44 is set and tied on the upper front side of the goods. Then the rope ring 52 is pulled to a vertical state, and the tongue 45 is inserted into the rope ring 52. The appropriate number is selected according to the front and rear distance of the goods. The rope ring 52 is passed through, and then the tying rope 44 that has passed through the rope ring 52 is tied to the upper rear side of the cargo again, and finally the tongue 45 is inserted into the corresponding insertion hole 46. During the insertion of the tongue 45 into the insertion hole 46, the front side inclined surface of the tongue 45 will squeeze the plug post 491 to move forward, and the plug post 491 is then inserted into the column hole 492 which is at the same axial position with it at this time, so that the reel 43 can be locked and limited, and then the tongue 45 is controlled to continue to move downward until the clamping strip 48 and the clamping slot 47 are on the same horizontal plane, and the clamping strip 48 is inserted into the clamping slot 47 to clamp the tongue 45 and limit the position, thereby completing the rapid bundling of the cargo (specifically as shown in the figure). Fig.12 Then repeat the above bundling operation for the second cargo entering the cargo elevator until all cargoes are bundled in the cargo elevator in turn.

[0044] In addition, the two strapping ropes 44 located on the upper part of the cargo may be crossed to form an X-shaped strapping method.

[0045] When the cargo elevator drives the cargo to the specified height, the car door 3 is first controlled to open, and the operator enters the car. Then, the operator kicks the push plate 9 backward with his foot or other means, and the push plate 9 then drives the column 63 to move backward. The column 63 then drives the clamping strip 48 to move backward, so that the clamping strip 48 is separated from the clamping slot 47. Then, the taut binding rope 44 pulls the plug tongue 45 to move out of the insertion hole 46, and the plug tongue 45 loses the squeeze on the plug column 491. The plug column 491 is pushed backward by the limit spring until the plug column 491 moves out of the insertion hole 46, and then the torsion spring resets and drives the reel 43 Reversing, the reel 43 then winds and retracts the lashing rope 44, which in turn drives the tongue 45 to move. When the tongue 45 moves to the position of the rope threading ring 52, the conical surface of the conical guide sleeve installed at the connection between the tongue 45 and the lashing rope 44 is used to ensure that the tongue 45 can smoothly pass through the rope threading ring 52 to avoid the tongue 45 and the rope threading ring 52 being stuck, until the lashing rope 44 is completely wound and retracted, the lashing rope 44 drives the tongue 45 to retract and reset to the installation groove 42, so that all the tied goods can be released at the same time, which greatly simplifies the steps of releasing the goods, and the goods will be pushed out of the freight elevator one by one later.

[0046] See also Figure 2 , Figure 5 and Figure 6 In this embodiment, the blocking mechanism 8 includes a sleeve 81 which is fixedly connected to the side wall of the car body 2 through a fixed block and has an opening at the top, and the sleeve 81 is placed horizontally. A plurality of sliding column seats 82 are slidably connected inside the sleeve 81, and a telescopic rod 83 is hinged to the outside of the sliding column seat 82 through a hinge ear block. A plurality of notch grooves 84 for placing the hinge ear blocks and clamping them are equidistantly provided on the sleeve 81 along its own axial direction. A docking block is fixedly connected to the end of the telescopic section of the telescopic rod 83, and a docking column is fixedly connected to the side of the docking block on the left away from the telescopic rod 83, and a docking groove matching the docking column is provided on the side of the docking block on the left away from the telescopic rod 83.

[0047] The initial state of the telescopic rod 83 is that it is slightly tilted against the side wall of the inner cavity of the freight elevator. In the process of pushing the goods into the freight elevator one by one, when a piece of goods enters the freight elevator, the corresponding left and right sliding column seats 82 are first moved to slide in the tube sleeve 81 to the rear side of the goods, and then a group of corresponding left and right sliding column seats 82 are moved to the front side of the goods. Then, the telescopic rod 83 is manually moved to drive the sliding column seat 82 to rotate in the tube sleeve 81 until the telescopic rod 83 rotates to a horizontal state. At this time, the telescopic rod 83 also drives the hinge ear block to move The telescopic rod 83 enters the corresponding notch groove 84 at this time, and the notch groove 84 is used to limit the hinge between the telescopic rod 83 and the sliding column seat 82, so that the telescopic rod 83 at this time cannot rotate around the sliding column seat 82. Then the telescopic rod 83 is pulled to extend, and the docking blocks at the ends of the left and right corresponding telescopic rods 83 move closer to each other until the docking column is inserted into the docking groove. After the two groups of left and right corresponding telescopic rods 83 are docked, they will contact the front and rear sides of the goods, so that the front and rear sides of the first goods put into the freight elevator can be blocked and limited.

[0048] For the subsequent goods that are put into the freight elevator in sequence, after each item is pushed into the freight elevator, a group of corresponding sliding column seats 82 on the left and right are moved to the front position of the goods, and then the above steps are repeated. The telescopic rod 83 is moved to drive the sliding column seat 82 to slide in the tube sleeve 81, so that the telescopic rod 83 becomes a horizontal state, and the hinge ear block slides into the corresponding notch groove 84 at this time, and then the two corresponding telescopic rods 83 on the left and right are pulled to connect with each other, so that the connected telescopic rods 83 touch the front side of the subsequent goods, so as to limit the goods put into the freight elevator from the front and rear directions, and ensure that the goods will not move in the freight elevator.

[0049] After the freight elevator drives the goods to the designated position, first push the group of telescopic rods 83 closest to the car door 3 to retract, so that the docking column and the docking groove are separated. After the telescopic rod 83 is retracted to the shortest state, the telescopic rod 83 is pushed in the opposite direction to drive the sliding column seat 82 to rotate, so that the hinge ear block moves out of the notch groove 84, until the telescopic rod 83 moves from the nine o'clock position of the tube sleeve 81 to the twelve o'clock position, and finally moves to the initial position. Then, the first cargo from the front can be moved out of the freight elevator, and the cargo can be moved out in sequence from front to back by controlling the corresponding telescopic rods 83 to reset from front to back.

[0050] See also Figure 2 and Figure 5 In this embodiment, the top limit mechanism 7 includes a connecting rod 71, a side push rod 72, an L-shaped groove 73, an L-shaped lever 74 and a strip frame 75. Rectangular grooves are provided at the lower parts of the left and right cavity walls of the car body 2. The upper groove wall of the rectangular groove is symmetrically hinged with a connecting rod 71 through a protrusion. The lower ends of the front and rear two connecting rods 71 ​​are fixedly connected to the side push rod 72. The front part of the car bottom of the car body 2 is symmetrically provided with two L-shaped grooves 73 with upper openings. The front groove wall of the L-shaped groove 73 is provided with a strip through groove. The L-shaped groove 73 and the strip through groove are slidably connected to an L-shaped lever 74 for cooperating with the car door 3. The long sections of the two L-shaped levers 74 are fixedly connected to the opposite sides with a strip frame 75 slidably set in the vertical section of the L-shaped groove 73, and the strip frame 75 is slidably sleeved on the outside of the side push rod 72.

[0051] After all the goods are put into the freight elevator, the car door 3 is controlled to close, and the two car doors 3 move closer to each other. After the car doors 3 move a certain distance, they will touch the L-shaped lever 74, and then push the two L-shaped levers 74 to move closer to each other. The L-shaped lever 74 then drives the bar frames 75 connected to them to move, and the bar plates then push the side push rods 72 to move, and the side push rods 72 then drive the connecting rods 71 ​​to rotate around the protrusions, so that the moving path of the side push rods 72 is an arc. During the movement of the side push rods 72 around the protrusions, they will contact the tying ropes 44 sections on the left and right sides of the goods, and squeeze the tying ropes 44 to further tighten the tying ropes 44, and then The side push rod 72 then contacts the side of the cargo. At this time, the two car doors 3 are also completely closed, realizing the limitation of the side of the cargo. After the cargo elevator drives the cargo to the specified position, the car door 3 is first controlled to open. During the opening process of the two car doors 3 moving away from each other, the L-shaped lever will gradually stop being pushed. Then the side push rod 72 drives the connecting rod 71 to rotate downward under its own weight, and at the same time, it will push the two bar frames 75 to move away from each other. The side push rod 72 is removed from the cargo, and the bar frame 75 drives the L-shaped lever 74 to move until the L-shaped lever 74 moves to the position when the car door 3 is open. Then the cargo can be moved out of the cargo elevator in turn.

[0052] The quick-binding part, the blocking mechanism 8 and the top limit mechanism 7 are combined with each other to limit the goods entering the freight elevator from multiple directions, ensuring that the goods remain in a stable state during the operation of the freight elevator.

[0053] During operation, the goods are first pushed into the freight elevator in sequence, and at the same time, the goods are quickly tied and limited by the cooperation of the winding mechanism 4 and the ring member 5. Whenever a cargo is pushed into the freight elevator, the front and rear sides of the cargo are blocked and limited by the blocking mechanism 8 until all the cargo are moved into the freight elevator. Finally, the car door 3 is controlled to be closed, and the top limit mechanism 7 is triggered to operate during the movement of the car door 3. The top limit mechanism 7 limits the cargo from the left and right sides, thereby limiting the cargo in multiple directions, avoiding the movement of the cargo during the operation of the freight elevator, and thus ensuring the stability of the operation of the freight elevator. After the freight elevator moves to the specified position, the car door 3 is opened, and the top limit mechanism 7 is triggered to move away from the cargo, and then the synchronous untying mechanism 6 is controlled to operate to release the fast bundling part from the cargo. Finally, the blocking mechanism 8 is controlled to move away from the cargo in sequence, and the cargo can be quickly taken out of the freight elevator.
