Description

Technical Field

[0001] The invention relates to a plane moving transporter, which is specifically suitable for clamping and transporting devices for cylindrical parts similar to tires and is often used in the technical field of mechanical parking equipment. Background Art

[0002] At present, the plane moving carrier in the existing mechanical parking equipment technology field includes a comb-toothed rectangular tube lifting tire carrier and a clamp arm clamp tire carrier.

[0003] The comb-toothed rectangular tube lifting tire transporter uses the lifting of the comb-toothed rectangular tube and the comb-toothed rectangular tube fixed on the parking space to complete the storage and retrieval of the car. However, this handling equipment has the following shortcomings: 1. The equipment is bulky and the thickness of the equipment is greater than 180mm; 2. The parking space rack requires a rectangular tube bracket with a fixed layer height, which will increase the total height of the steel structure equipment and the total cost of the garage; 3. The distance between the front and rear comb teeth is fixed, which has poor applicability to vehicles; 4. The equipment has many comb teeth exchange actions during operation, and the overall handling efficiency is relatively low.

There are the following shortcomings: the clamp arm is a clamp-type clamp to clamp the tire, the clamp arm can only complete the rotation action, and it is impossible to realize the clamp arm to clamp and lift the tire in parallel.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention adopts hydraulic power and hydraulic oil cylinder to realize parallel clamping after the wheel clamp is rotated, and its power is strong, and the operation is efficient and reliable. Therefore, the design has strong power, efficient operation and high reliability.

[0032] 2. A single wheel clamp in a plane moving transporter of the present invention is controlled by two oil cylinders, with high control accuracy, which can not only realize the rotation of the wheel clamp, but also realize the parallel clamping action of the wheel clamp, ensuring that the wheel clamp maintains a larger contact surface with the clamped tire, avoiding damage to the tire by the clamping action. Therefore, this design can realize the parallel clamping action, effectively avoiding damage to the tire during the handling project.

[0033] 3. The wheel clamp in the plane mobile carrier of the present invention is hydraulically driven, and the hydraulic cylinder is placed flat in the transport wheel vehicle. Compared with the traditional motor-driven transmission mode with a reducer, gear or sprocket set, the present design can significantly reduce the thickness of the carrier. Its design thickness is 60-100mm, which can be better suitable for vehicles with lower chassis and shorter wheelbase, so that it can be better suitable for the transportation of different models. At the same time, two independent carriers are required to work together when transporting vehicles. The independently set carriers are flexible to match and have a high degree of freedom in operation. Therefore, the carrier of the present design adopts an ultra-thin design and can be applied to the transportation of most models. At the same time, the carriers are independently set, and the degree of freedom of collaborative operation is high.

[0034] 4. The present invention uses a reversing valve and an on-off solenoid valve to control the piston extension and contraction of the rotating oil cylinder and the clamping oil cylinder, thereby controlling the rotation and movement of the wheel clamp. Compared with the traditional motor drive mode, the reversing operation is smoother; at the same time, by setting a relief valve, the system overload can be effectively avoided, the overall structure is simpler and more reliable, and the control circuit is simplified. Therefore, the present design controls the rotation and movement of the wheel clamp through a reversing valve and an on-off solenoid valve, and prevents the hydraulic system from overloading by setting a relief valve. The reversing operation is smooth, the overall structure is simple and reliable, and the control circuit is simplified. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The principle of the present invention is described as follows:

[0069] When the carrier is in the initial retracted state, the carrier is started, the hydraulic power pack works, the oil is supplied to the rod chamber of the rotating oil cylinder, the oil is supplied to the rodless chamber of the clamping oil cylinder through the valve group, the piston rod of the rotating oil cylinder is retracted, and the clamp arm rotates until the two clamp bodies are parallel to each other, and the carrier is in the state of the clamp arm being extended.

[0070] The hydraulic power pack continues to provide hydraulic energy, the rodless chamber of the rotating oil cylinder gets oil, and the rod chamber of the clamping oil cylinder gets oil, so that the piston rod of the clamping oil cylinder retracts and the piston rod of the rotating oil cylinder is pushed out. Under the action of the valve group, the clamping arms move in parallel. The left and right clamping arms move in parallel towards each other, and the car tire is lifted by the parallel clamp.

When there is no pressure inside the cylinders, the telescopic rods of the cylinders are all in an extended state, and the wheel clamps 3 of the carrier are retracted.

[0072] The first on-off solenoid valve 441 , the second on-off solenoid valve 442 , the third on-off solenoid valve 541 and the fourth on-off solenoid valve 542 are all normally open two-position two-way solenoid valves.

[0073] The one-way throttle valve 414 allows the oil cylinder to run smoothly, the pressure gauge 49 is used to detect the system pressure, and the single relief valve 46 releases pressure when the hydraulic system pressure is too high to avoid system overload.

[0074] The working principle of the carrier is as follows: the motors of the left boost pump 42 and the right boost pump 52 are turned on and high-pressure oil is sent to the hydraulic system. At this time, the right electromagnet of the first reversing valve 431 is energized, the first reversing valve 431 works in the right position, and the hydraulic oil flows out from the second working oil port of the first reversing valve 431 and enters the rod chamber of the first left rotating cylinder 21. The piston of the first left rotating cylinder 21 retracts and drives the first left wheel clamp 31 to rotate until the first left wheel clamp 31 is perpendicular to the first side plate 11; at the same time, the fifth reversing valve 531 controls the piston of the first right rotating cylinder 23 to retract and drives the first right wheel clamp 32 to rotate, so that the first right wheel clamp 32 is perpendicular to the first side plate 11, and the first left wheel clamp 31 is parallel to the first right wheel clamp 32;

[0075] Subsequently, the left electromagnet of the first reversing valve 431 is energized and the right electromagnet is de-energized, the right electromagnet of the second reversing valve 432 is energized, the electromagnet of the first on-off solenoid valve 441 is energized, and the first on-off solenoid valve 441 is turned on. At this time, the first reversing valve 431 works in the left position, and the hydraulic oil flows out from the first working oil port of the first reversing valve 431 and enters the rodless chamber of the first left rotating cylinder 21, and the piston of the first left rotating cylinder 21 extends; at the same time, since the first on-off solenoid valve 441 is turned on, the first left rotating cylinder 21 The hydraulic oil in the rod chamber of the cylinder 21 is squeezed into the rod chamber of the first left clamping cylinder 22, and the piston of the first left clamping cylinder 22 retracts. At this time, the first left rotating cylinder 21 and the first left clamping cylinder 22 jointly drive the first left wheel clamp 31 to move toward the middle of the carrier; at the same time, the fifth reversing valve 531, the sixth reversing valve 532 and the third on-off solenoid valve 541 control the first right wheel clamp 32 to move toward the middle of the carrier, and the first left wheel clamp 31 and the first right wheel clamp 32 close to lift the tire.

[0076] The working principles of the second left wheel clamp 33 and the second right wheel clamp 34 are the same as the working principles of the first left wheel clamp 31 and the first right wheel clamp 32 .
