Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a waste transfer cart for building construction. Background Art

[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of handcarts is constantly developing, handcarts are still used as indispensable transport tools. Handcarts are widely used in production and life because they are low in cost, simple in maintenance, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use. They are very convenient for transporting lighter items over short distances. A handcart is also often used in construction.

[0003] The wheelbarrows used in construction are generally used to transport abandoned construction waste. When transporting construction waste, construction workers often want to reduce the number of waste transports, so they pile up a large amount of waste in the wheelbarrow at one time. The wheelbarrow itself has a relatively simple structure and can only be used for short distances. Its own anti-tilt ability is average. When the wheelbarrow is overloaded, the center of gravity of the vehicle body may shift, the balance of the vehicle body is difficult to control, and it is easy to roll over when turning. There are certain safety hazards during use;

[0004] Therefore, a kind of construction waste transfer cart is specially proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a waste transfer cart for construction, which has the advantages of preventing the cart from being overloaded and improving the safety of the cart. It solves the problem that the balance of the existing cart is difficult to control when it is overloaded, which makes safety accidents prone to occur.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction waste transfer cart, comprising a basket, a group of hand push rods are fixedly installed at the front and rear ends of the right side of the basket, a card slot is opened at the bottom of the left inner wall of the basket, a spring chamber is opened on the upper inner wall of the card slot, a blocking plate is movably installed inside the spring chamber, a spring is fixedly installed on the top of the blocking plate, and a support rod is fixedly installed on the right side of the bottom of the basket;

[0007] A load-bearing plate is movably installed at the bottom of the interior of the basket, the right side of the load-bearing plate is movably connected to the bottom of the right inner wall of the basket, and the left side of the load-bearing plate is clamped in the interior of the clamping slot.

[0008] Preferably, the bottom of the object-blocking plate is located above the load-bearing plate, and the bottom of the object-blocking plate can move along with the movement of the load-bearing plate due to the spring at the top, and the bottom of the object-blocking plate is in close contact with the load-bearing plate below.

[0009] Preferably, inverted tripods are fixedly installed at the front and rear ends of the bottom of the basket, a cross bar is fixedly installed between two groups of the inverted tripods, and a supporting shock-absorbing component is provided in the middle of the cross bar.

[0010] Preferably, the supporting shock absorbing component includes a mounting plate, which is fixedly mounted at the middle position of the cross bar, and two groups of hydraulic rods are fixedly mounted on the top of the mounting plate, and a group of spring shock absorbers are fixedly mounted on the outside of the two groups of hydraulic rods on the top of the mounting plate.

[0011] Preferably, the tops of the hydraulic rod and the spring shock absorber are fixedly connected to the bottom of the load-bearing plate.

[0012] Preferably, a wheel is movably mounted on the surface of the crossbar between the mounting plate and the inverted tripod, and a bearing is provided at the mounting point of the wheel and the crossbar and the wheel rotates by the bearing.

[0013] Preferably, the two groups of wheels are both located at the bottom of the load-bearing plate, and under normal conditions, the tops of the wheels do not fit the bottom of the load-bearing plate.

[0014] Preferably, the hydraulic rod and the spring shock absorber push the load-bearing plate upwards, and when the weight borne by the load-bearing plate exceeds the supporting force of the hydraulic rod and the spring shock absorber at the bottom of the load-bearing plate, the load-bearing plate descends to fit the wheels at the bottom.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. This waste transfer cart for construction use is equipped with a basket, a card slot, a load-bearing plate, wheels, a supporting shock-absorbing component, a mounting plate, a hydraulic rod, a spring shock absorber and other devices, so as to prevent the cart from being overloaded and improve the safety of the cart.

[0017] 2. This kind of construction waste transfer cart has a mounting plate whose top is connected to the load-bearing plate by a hydraulic rod and a spring shock absorber. When the basket is jolted during pushing, the hydraulic rod and the spring shock absorber can be used to absorb energy and reduce shock, so that the load-bearing plate can shake slightly, which also reduces the vibration energy, thereby preventing the basket from vibrating significantly when passing through speed bumps and potholes, thereby reducing the chance of construction waste falling from the basket. The cart can also be slowed down actively when encountering larger bumps. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 4 , the utility model provides a technical solution:

[0027] A waste transfer cart for construction, comprising a basket 1, a group of hand push rods 2 are fixedly installed at the front and rear ends of the right side of the basket 1, a slot 3 is provided at the bottom of the left inner wall of the basket 1, a spring chamber 5 is provided on the upper inner wall of the slot 3, a blocking plate 6 is movably installed inside the spring chamber 5, a spring 7 is fixedly installed on the top of the blocking plate 6, a support rod 12 is fixedly installed on the right side of the bottom of the basket 1, a load-bearing plate 4 is movably installed at the bottom of the basket 1, the right side of the load-bearing plate 4 is movably connected to the bottom of the right inner wall of the basket 1, the left side of the load-bearing plate 4 is clamped in the slot 3, and the bottom of the blocking plate 6 is located above the load-bearing plate 4 The bottom of the blocking plate 6 can move with the movement of the load-bearing plate 4 due to the spring 7 on the top, and the bottom of the blocking plate 6 is in close contact with the load-bearing plate 4 below. The front and rear ends of the bottom of the basket 1 are fixedly installed with inverted tripods 8, and a cross bar 9 is fixedly installed between the two groups of inverted tripods 8. A supporting shock-absorbing component 11 is provided in the middle of the cross bar 9. The supporting shock-absorbing component 11 includes a mounting plate 111, and the mounting plate 111 is fixedly installed in the middle position of the cross bar 9. Two groups of hydraulic rods 112 are fixedly installed on the top of the mounting plate 111. A group of spring shock absorbers 113 are fixedly installed on the outside of the two groups of hydraulic rods 112 at the top of the mounting plate 111.

[0028] By adopting the above technical scheme, when in use, the load-bearing plate 4 is always in an upward state due to the top force of the bottom hydraulic rod 112 and the spring shock absorber 113, and there is a certain distance between the load-bearing plate 4 and the bottom wheel 10. The object blocking plate 6 always has a downward force due to the existence of the top spring 7, so that the bottom of the object blocking plate 6 always fits with the surface of the load-bearing plate 4. When construction waste is put into the vehicle basket 1 during use, the load-bearing plate 4 will not move downward within the load-bearing range. For example, if the load-bearing range of the device is 50 kg, then within 50 kg, the force provided by the hydraulic rod 112 and the spring shock absorber 113 to the load-bearing plate 4 can ensure that the load-bearing plate 4 will not move downward and fit with the bottom wheel 10, and can be used normally. If the construction waste loaded in the vehicle basket 1 exceeds 50 kg, exceeding the hydraulic rod 112 and the spring shock absorber 113, the load-bearing plate 4 will not move downward and fit with the bottom wheel 10, and can be used normally. When the shock absorber 113 provides force for the load-bearing plate 4, the load-bearing plate 4 will drop, causing the bottom of the load-bearing plate 4 to fit with the wheel 10, making it impossible to use the device normally. During the downward movement of the load-bearing plate 4, the spring chamber 5 always remains in contact with the load-bearing plate 4 due to the blocking plate 6, preventing garbage from entering the card slot 3 and affecting the subsequent resetting of the load-bearing plate 4. When the load-bearing plate 4 drops and fits with the wheel 10 and cannot push the device normally, it is necessary to take out the construction waste in the basket 1 until the construction waste in the basket 1 is within 50 kilograms. The hydraulic rod 112 and the spring shock absorber 113 raise and reset the load-bearing plate 4 again and no longer fit with the wheel 10. At this time, the device can be pushed by the hand push rod 2. Through the above design, the device cannot be overloaded during use, thereby avoiding the problem of safety accidents caused by overloading the device.

[0029] Specifically, Figures 2 to 4 As shown, the tops of the hydraulic rod 112 and the spring shock absorber 113 are fixedly connected to the bottom of the load-bearing plate 4, and the surface of the cross bar 9 is movably mounted with wheels 10 between the mounting plate 111 and the inverted tripod 8. The mounting locations of the wheels 10 and the cross bar 9 are provided with bearings 101 and rotate on the bearings 101. Both groups of the wheels 10 are located at the bottom of the load-bearing plate 4. Under normal conditions, the tops of the wheels 10 do not fit into the bottom of the load-bearing plate 4, and the hydraulic rod 112 and the spring shock absorber 113 push the load-bearing plate 4 upward. When the weight borne by the load-bearing plate 4 exceeds the supporting force of the hydraulic rod 112 and the spring shock absorber 113 at the bottom of the load-bearing plate 4, the load-bearing plate 4 descends and fits into the wheels 10 at the bottom.

[0030] By adopting the above technical solution, the existing wheelbarrow does not have a shock-absorbing function when in use. When the vehicle is full of construction waste, the pusher needs to be careful to push the vehicle slowly when passing through speed bumps and potholes. If the speed is too fast, the construction waste in the basket 1 is easily thrown out, and the construction waste needs to be picked up again. The device solves this problem by arranging a supporting shock-absorbing component 11 on the cross bar 9. The top of the mounting plate 111 is connected to the load-bearing plate 4 through a hydraulic rod 112 and a spring shock absorber 113. When the basket 1 is bumpy during pushing, the hydraulic rod 112 and the spring shock absorber can be used to The device 113 absorbs energy and reduces shock, causing the load-bearing plate 4 to shake slightly, which also reduces the shock energy, thereby preventing the basket 1 from vibrating significantly when passing through speed bumps and potholes, thereby reducing the chance of construction waste falling from the basket 1. When the basket 1 is bumped during pushing, the load-bearing plate 4 will briefly contact the wheel 10 at the bottom when it descends to the deepest point. Therefore, the moving cart can be decelerated to a certain extent, thereby allowing the basket 1 to maintain a relatively slow travel speed when passing through bumpy road conditions, further improving the safety of the device during use.

[0031] Working principle: During use, construction waste is placed in the basket 1. When placing construction waste, overloading is not allowed. For example, if the load-bearing capacity provided by the hydraulic rod 112 and the spring shock absorber 113 for the load-bearing plate 4 is 50 kg, then the basket 1 can only be loaded with construction waste within 50 kg. When the construction waste loaded in the basket 1 exceeds 50 kg, the hydraulic rod 112 and the spring shock absorber 113 at the bottom of the load-bearing plate 4 are insufficient to support the load-bearing plate 4, and the load-bearing plate 4 will drop, causing the load-bearing plate 4 to contact the wheel 10 at the bottom, thereby failing to load the construction waste. The basket 1 cannot be pushed normally, so the device cannot be overloaded when in use. If the basket 1 encounters a speed bump or a pothole in the forward process, the hydraulic rod 112, the spring shock absorber 113 and the load-bearing plate 4 can achieve a shock-absorbing effect. Therefore, it can avoid the situation where the construction waste loaded in the basket 1 is shaken off due to the bumps in the forward process, and the device can be decelerated when encountering strong bumps. The basket 1 is pushed forward by the push rod 2, and the support rod 12 is lifted off the ground. When stopping, the device is positioned with the help of the support rod 12.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
