Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to a trolley for engineering construction. Background Technology

[0002] A handcart is a transport vehicle that is pushed and pulled by human power. It is the ancestor of all vehicles. Although the material handling technology of handcarts has been continuously developed, handcarts are still used as an indispensable transport tool. In small construction sites, it is often necessary to use handcarts to transport materials. Handcarts are widely used because they are inexpensive, easy to maintain, easy to operate, and lightweight. In the current technology, when the handcart stops pushing to transport materials, it usually uses two support legs near the end of the push handle to support the cart to ensure the balance of the handcart.

[0003] In the prior art, the patent with authorization announcement number CN221068135U discloses a trolley for engineering construction. The trolley provides support for the truck bed by forming an isosceles triangle structure through the cooperation of the support wheel and the walking wheel. When the brake plate is engaged with the brake chuck, the support wheel cannot rotate and the support wheel restricts the movement of the device. When the drive disc causes the connecting rod to lift the brake plate, the support wheel can rotate. At the same time, the limit rod is no longer connected to the connecting seat, so that the device can be directly pushed to move without controlling the balance of the vehicle, which is convenient to use.

[0004] This device replaces the two support legs at the bottom of the cart with outrigger wheels, forming a triangular structure with the driving wheels to achieve balance when the vehicle is stopped. However, the support wheels have a small contact area with the ground and low friction, making them prone to sliding along the ground when the cart is stopped, resulting in poor balance. This is especially noticeable when the cart is parked on a sloping surface, affecting its practicality. Therefore, a construction cart was designed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a trolley for engineering construction.

[0006] The technical problem to be solved by this utility model is to provide a trolley for engineering construction, which solves the problem that in the prior art, the trolley achieves balance when the vehicle stops and is pushed by replacing the two support legs at the bottom of the cart with outrigger wheels. However, the support wheels have low friction with the ground and are prone to sliding along the ground, resulting in poor stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a construction trolley, comprising a bucket, wheels, push handles, support legs, and a cross plate. The wheels are rotatably connected to the right side of the bottom surface of the bucket, and two push handles are fixedly installed above the left side surface of the bucket. Support legs are welded to both the inner and outer ends of the bottom left side of the bucket, and a cross plate is rotatably installed between the two support legs via a pin.

[0008] Preferably, when the support leg is perpendicular to the horizontal plane, the cross plate is horizontal.

[0009] Preferably, the bottom horizontal height of the cross plate is lower than the bottom horizontal height of the support leg.

[0010] Preferably, the bottom surface of the horizontal plate has multiple anti-slip stripes.

[0011] Preferably, a material blocking assembly to prevent the fluid material inside the truck bed is fixedly installed inside the truck bed. The material blocking assembly includes inclined rods fixed on the inner and outer sides of the center of the upper surface of the truck bed and a baffle plate that slides between the two inclined rods. Each of the two inclined rods is provided with a sliding groove. A slider is fixedly provided on the top of the inner and outer sides of the baffle plate, and the slider slides in the sliding groove.

[0012] Preferably, the diagonal bar is inclined to the upper right and is parallel to the right end of the interior of the truck bed.

[0013] Preferably, the baffle plate and the diagonal bar are parallel to each other, and the width of the baffle plate is equal to the internal width of the truck bed.

[0014] Preferably, when the slider slides to the bottom of the chute, the baffle plate extends into the truck bed, and the bottom horizontal height of the baffle plate is higher than the bottom horizontal height of the truck bed. When the slider slides to the bottom of the chute, the bottom horizontal height of the baffle plate is equal to the upper surface horizontal height of the truck bed.

[0015] Preferably, a limiting plate is fixedly provided on the side of the slider away from the blocking plate, the limiting plate is attached to the outer surface of the inclined rod, and the width of the limiting plate is greater than the width of the groove.

[0016] Preferably, multiple mounting grooves are provided on both sides of the slider, and multiple rotating rollers are rotatably arranged in the mounting grooves, with the rotating rollers rolling on both sides of the groove.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] 1. This utility model features a horizontal plate. When the trolley stops pushing or is loaded with materials, the horizontal plate under the support legs contacts the ground, and the anti-slip stripes at the bottom of the horizontal plate also contact the ground, increasing the friction between the horizontal plate, the anti-slip stripes, and the ground. This ensures the stability of the trolley when it stops pushing or is loaded with materials, making it more convenient to use. Furthermore, the horizontal plate is rotatably mounted between the two support legs via a pin, facilitating contact between the horizontal plate and the inclined ground.

[0019] 2. This utility model, by incorporating a blocking component, allows the slider on the blocking plate to slide to the bottom of the chute when the trolley is being pushed normally. At this point, the blocking plate extends into the hopper, separating the liquid material inside and reducing the tendency for the liquid material to sway. This reduces the magnitude of the change in the center of gravity within the hopper, ensuring the stability of the trolley when it is being pushed. Furthermore, when the trolley is tilted to the right to unload, the slider slides along the chute to the top of the chute under the weight of the blocking plate. At this point, the bottom of the blocking plate is at the same level as the bottom of the hopper, preventing the liquid material from being discharged from the right end of the hopper and increasing its practicality.

[0020] 3. This utility model sets a limiting plate, which can limit the position of the slider sliding in the groove, ensuring the stability of the slider sliding in the groove. By setting a rotating roller, which is fixed to both sides of the groove, the friction of the slider sliding in the groove can be reduced, making it easier for the slider to slide along the groove. This makes it easier to adjust the position of the blocking plate to achieve the effect of blocking materials and facilitating unloading. Attached Figure Description

[0028] Example:

[0029] like Figures 1-4 As shown, an embodiment of this utility model provides a trolley for engineering construction, including a trolley 1, wheels 2, push handles 3, support legs 4, and a cross plate 5. The wheels 2 are rotatably connected to the right side of the bottom surface of the trolley 1. Two push handles 3 are fixedly installed above the left side surface of the trolley 1. Support legs 4 are welded to both the inner and outer ends of the bottom left side of the trolley 1. A cross plate 5 is rotatably installed between the two support legs 4 via a pin.

[0030] In this embodiment, when the support leg 4 is perpendicular to the horizontal plane, the horizontal plate 5 is horizontal, which makes it convenient for the horizontal plate 5 to contact the ground.

[0031] In this embodiment, the bottom horizontal height of the horizontal plate 5 is lower than the bottom horizontal height of the support leg 4, which facilitates the horizontal plate 5 contacting the ground, increases the contact between the horizontal plate 5 at the bottom of the support leg 4 and the ground when the trolley stops pushing, and increases the stability of the trolley when it stops pushing.

[0032] In this embodiment, multiple anti-slip stripes 501 are provided on the bottom surface of the horizontal plate 5 to further increase the friction coefficient of the bottom surface of the horizontal plate 5 and increase the friction between the horizontal plate and the ground.

[0033] By providing a horizontal plate 5, when the trolley stops pushing or is loaded with materials, the horizontal plate 5 below the support legs 4 contacts the ground, and the anti-slip stripes 501 at the bottom of the horizontal plate 5 also contact the ground, increasing the friction between the horizontal plate 5, the anti-slip stripes 501, and the ground, ensuring the stability of the trolley when it stops pushing or is loaded with materials, making it more convenient to use. In addition, the horizontal plate 5 is rotatably set between the two support legs 4 via a pin shaft, making it easy for the horizontal plate 5 to contact the inclined ground.

[0034] In this embodiment, a material blocking component is fixedly installed inside the truck bed 1 to prevent the fluid material inside the truck bed 1 from shaking. The material blocking component includes inclined rods 6 fixed on the inner and outer sides of the center of the upper surface of the truck bed 1 and a baffle plate 7 sliding between the two inclined rods 6. Each of the two inclined rods 6 is provided with a sliding groove 601. A slider 701 is fixedly provided on the top of the inner and outer sides of the baffle plate 7, and the slider 701 slides in the sliding groove 601.

[0035] In this embodiment, the diagonal bar 6 is inclined to the upper right, and the diagonal bar 6 is parallel to the inner right end of the truck bed 1.

[0036] In this embodiment, the baffle plate 7 and the diagonal bar 6 are parallel to each other, and the width of the baffle plate 7 is equal to the internal width of the truck bed 1.

[0037] In this embodiment, when the slider 701 slides to the bottom of the chute 601, the baffle plate 7 extends into the truck bed 1, and the bottom horizontal height of the baffle plate 7 is higher than the bottom horizontal height of the truck bed 1. When the slider 701 slides to the bottom of the chute 601, the bottom horizontal height of the baffle plate 7 is equal to the upper surface horizontal height of the truck bed 1.

[0038] By incorporating a blocking component, when the trolley is pushed normally, the slider 701 on the blocking plate 7 slides to the bottom of the chute 601. At this time, the blocking plate 7 extends into the hopper 1, separating the liquid material inside the hopper 1. This reduces the tendency of the liquid material inside the hopper 1 to sway, thereby reducing the amplitude of the center of gravity change inside the hopper 1 and ensuring the stability of the trolley when it is pushed. When the trolley is tilted to the right to unload, the slider 701 slides along the chute 601 to the top of the chute 601 under the action of the weight of the blocking plate 7. At this time, the bottom horizontal height of the blocking plate 7 is equal to the bottom horizontal height of the hopper 1. The blocking plate 7 will not block the liquid material from being discharged from the right end of the hopper 1, increasing its practicality.

[0039] In this embodiment, a limiting plate 702 is fixedly provided on the side of the slider 701 away from the blocking plate 7. The limiting plate 702 is attached to the outer surface of the inclined rod 6, and the width of the limiting plate 702 is greater than the width of the slide groove 601. The limiting plate 702 can ensure the stability of the slider 701 sliding in the slide groove 601.

[0040] In this embodiment, multiple mounting grooves 703 are provided on both sides of the slider 701. Multiple rotating rollers 704 are rotatably arranged in the mounting grooves 703. The rotating rollers 704 roll on both sides of the slide groove 601. The arrangement of the rotating rollers 704 can reduce the friction between the slider 701 and the slide groove 601, making it easier for the slider 701 to slide along the slide groove 601.

[0041] By setting a limiting plate 702, the limiting plate 702 can limit the position of the slider 701 sliding in the slide groove 601, ensuring the stability of the slider 701 sliding in the slide groove 601. By setting a rotating roller 704, the rotating roller 704 is fixed to both sides of the slide groove 601, which can reduce the friction of the slider 701 sliding in the slide groove 601, making it easier for the slider 701 to slide along the slide groove 601. This makes it easier to adjust the position of the blocking plate 7 to achieve the effect of blocking materials and facilitating unloading.

[0042] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
